“An African farmer” … because he's in Africa? You could say that with a location. If you're using African to describe his appearance though, you should change that. Africa is very diverse and they don't all look the same, so the description doesn't give me anything to go on for his appearance. You can call him black, it's not a bad word, although “olive-skinned” or “with skin like burnt chocolate” are good too

“His eyes [opened wide] as if he [had] struck gold” … although you could take out the Telling and make this part of the next paragraph, “His eyes opened wide and he jumped, “I am rich!””

“All he had to do [was pick the rock] up and take [it] to a diamond store”

“to contact Alice who was also a friend of his” … WHAT. I'm finding it hard to believe that Alice happens to know some guy in Africa who happens to find something which I bet is important to the plot somehow

“But it is [stuck] on some kind”

“She needed to see it [first, before Alexander and Alpha came] to check it out” … but why does she want Alex to check it out? There is no reason for her to think it has anything to do with them

“She arrived at the plantation where Adam waited for her” … this should be a new paragraph, or even a new scene, since I assume some time passed while she was driving

“At the left corner of my plantation, please follow me! Alice followed Adam to the left corner of the plantation” … too much repetition close together. Maybe, “''At the left corner of my plantation, please come with me!'' Alice followed Adam. {Next paragraph} When they got to the diamond”

“She wondered how and why that diamond was on that metal pipe. No one lived at that area before Adam” … is that second sentence something Alice knows, or something she is assuming?

“Maybe you could [help] us find out what it is” … I think?

“Alexander now fifteen was at the school's library” … before you were trusting the reader to understand how much time was passing between chapters by simply giving the date. So this feels weird, interrupting a sentence to Tell how old he is. Not to mention it's an awkward interruption

“home world of the Aquamaids and where Helen and Fabocusa enjoyed their own honeymoon” … aw, gross. I just realized Alex's parents conceived him on the same planet that his love interest is from, meaning Vyla's ancestors probably watched them do it … no, I don't know why that grosses me out

“The first group were the [Flipperkeys. They lived in coral reefs and tidal regions of the planet, burrowed in sands, fed on critters that lived around the ocean bed, and had limbs like frogs. The second group were the Bedleaperians, which could leap through the air or swim in the water or walk along the ocean bed. They looked like aquatic versions of chimps, banoboos, gorillas, and orangutans. And the third group were the Whalmanoids, which spent most of their lives swimming in the open waters or sometimes dwelling] in the shallow zones” … interesting, and I suppose this is a nice subtle way to show Alex's growing interest in Vyla

“their eyes met. ''Hey,'' Vila giggled. ''Hey,'' Alexander smiled” … I'm so happy knowing these two are gonna have sex

“Vila chuckled and said, ''I could use you as a reference.'' Alexander smiled, ''Maybe you could” … so much sex! Have you considered just writing this kind of teen romance stuff all the time? Every page would be like this and it would be wonderful

“a tall hefty Italian boy … a Mexican kid with a short [mohawk]” … and again, nationality does NOT give the reader appearance, that would be stereotyping. While “a tall, hefty boy with sun-bleached hair” and “a brown-skinned, thin kid with a short mohawk” is fine. Do a search for Italian and Mexican to remove all the others in this chapter. And why is it only these Earth nationalities on Purlif? Where's the alien nationalities?

“Man that girl is fucking hot! … I know right! God, Aquamaid girls are born super hot! … They have the best sets of titties” … lololololololololololololololololololololololololololololololololololololololol

“Especially [Vyla,'' said the tallest of the three with a smile. Everyone called] him the Flash because he was the fastest Human in the basketball league. Alexander stopped to hear what else they said] about his best friend” … but meh, now this feels like an after-school special. Oh no, idiots are being idiots! Only the Good Boy can save the day!

“Every time I see her walk by, I get a boner … Guys, there is a thing we call sharing” … okay, the Flash is seriously my favorite new character. He's so open and single-minded in his lust, not shy or awkward like most teens. I know he's supposed to be a jerk, but I feel like he's just a fun-loving hippy type guy

“Then he started having flashbacks about his mother being molested and tortured by her master and men during her slave years” … um, I'm not sure about having flashbacks just from hearing about terrible things? I get Alex not liking what they are saying, and he could totally be mad at these guys for treating Vyla like an object because his own mother was a sex slave, but flashbacks is too much

“the more Alexander's Spacer blood boiled” … his Spacer blood? If anything, I would think his Human blood would be boiling, or better yet “the more Alexander's blood boiled”

“When we go to the bed, I will first go for her large tits, play with her pussy, and then stick it in as if she is a jack hammer” … oh Flash, your lust is so pure, so honest. As for you Brenden, I did not believe you could write like this!

“HOW DARE YOU SAY THOSE THINGS YOU WANT TO DO TO MY BEST FRIEND! SHE WOULD NEVER DO ANYTHING LIKE THAT!” … I love how mad Alex is, BUT with how mad he is, I can't see him talking in such long, formal sentences. Maybe, “How dare you say that! She is my best friend! She would never do that!”

“Alexander snared” … snarled

“My mother was abused because assholes like you messed around with girls! Vila will never fall for any of you guys! You should show respect to her and everyone else, understand?!” … yeah! You tell them Alex! The Flash is still my favorite, but he just got schooled by Alex!

“The Flash [didn't] say [anything. Then] Alexander heard something dripping down [to] the floor. He looked down and realized that the Flash [had peed] in fear” … less Telling this way

“But [his family's past still] haunted [him. He] vowed to not let it haunt him [any] more” … although I don't like this line using haunted twice in a row. Maybe, “He vowed never to let the past control his actions like that again.”

“they [see] her as a sex tool” … also, did you mean sex toy?

“It is my stressful life as the only Human/Spacer hybrid alive” … um, there's not really anything stressful about it? He's been mopey and sad, and I sort of understand that. But so far he hasn't faced any stressful challenges from being a Spacer-Human. In fact the big brain seems pretty useful for school

“Just relax and think about happy things while heading back home” … oh, interesting advice! What is Alex's happy thought? Somehow I think it might be Vyla

“the hover bus, [thankful] to be home”

“Should I ask you that ask you that question as soon as you come home?” … what? I think there's some repeated words here, but also what is she saying? Judging by his response, something like, “Hey, I wanted to ask that question first!”

“Alpha and I are the only ones who can figure it out” … no, this is magical thinking. How about this: the news does a close-up of the pipe, and Alex or Alpha notice some Spacer glyphs. So that's how they know Alex and Alpha need to check it out. And that way Adam doesn't need to be Alice's friend somehow. So the chapter starts with Adam discovering the artifact and calling for the news crews, then moves to Alex's day at school, and when he gets home he sees the news report and Alpha recognizes the artifact as Spacer tech and so they go to see it. And it's not an unbelievable series of coincidences that way

“We should probably wait until night [falls, when] they are not [digging. That way the paparazzi won't] surround us”

“Since I am a hybrid between Human and Spacer and Alpha is a Spacer Monitor, everyone would be questioning about how we know what this artifact could be and what is its purpose. Anything bad could happen between us” … what? I don't even understand what he is saying. You could just delete this. Going at night when there isn't a lot of people around is a good enough reason

“Alice smiled. ''We are so glad that to be here” … huh? What is she glad about?

“I am a crossbreed between Human and Spacer” … whoa, no, Alex does not need to explain all this. Adam was confused, but I don't see him needing the whole story. You could trim down quite a lot here, especially the next six paragraphs. Basically they just go to the field and inspect the “diamond” and give Adam the minimum necessary info

“Since Alexander and I know about the Spacers, we could figure out what it is” … I still don't see why that would be. There hasn't been any reason yet in the story to think the artifact is Spacer tech

“[They all left] the house to investigate [the artifact]. As they got to the site, their mouths dropped with amazement. [The digging crews had been busy today, and it was fully uncovered.] {New paragraph} The artifact was about the size of a medium-sized square house. [It looked like] a silver pyramid with a short metal pipe on top. On the short metal pipe was the giant diamond that Adam first dug up”

“You found a maintenance control system of the Spacers' gate,'' said Alpha. ''What is a gate?'' Adam asked Alpha” … WAIT! This is part of the gate Seiton mentioned in the last chapter? Meaning that randomly finding it in the middle of some guy's field is very, very bad? This is way too much of a coincidence, but at least now I'm interested

“If they are, we can put these pieces back together while we are still on the surface” … okay, but I really doubt the local news and astrological agencies would miss several orbiting planetoids moving around and forming a big gate all of a sudden

“Not many people would spend a lot time waiting to get to their location if they use it” … except humans already have teleportation? Is the gate better? I don't understand Alex being excited

“He looked [for somewhere that] he could place the index to turn on the power”

“His Index started to glow blue [and move under his shirt as he approached. When he pulled the Index out and touched it to the gem on the wall], a large holographic screen popped up”

“The diagrams and images showed red shades and marks on the structures of the [gate, showing where] the gate was severely damaged. [Alpha] made the screen show a map of the planet and its two [moons. Several of the orbiting planetoids were highlighted in red by the screen. {Next paragraph} ''Those planetoids are actually fragments of the gate,'' said Alpha, pointing to the screen.]”

“Then Alexander thought about Seiton. Seiton was still in the Spacer network trying to find and kill him. Trying to fix up the gate brought fear into him. If they fix up the gate, Seiton would come after him … Alexander remembered the Spacer's extinction happened on Pandora thousands of years ago and he and his mother were the only survivors of that event. This gate should not be opened” … you don't need to Tell me all this when everything Alex says Shows it

“But if we do, [we've] got to stay away from that world” or “But if we do, we [need] to stay away from that world”

“you [can't] tell anyone about what this structure is. No would [knows] how to activate it since he has the Index”

“The [gate was] a gateway to hell”

Neat chapter! Alex getting all jealous because Vyla is apparently the hottest girl ever and everyone wants her is pretty great, and now the Flash can show up again as a reformed guy. Seriously, you should consider writing more in that teen romance genre, you rock at it! But don't use nationalities to describe people, that's stereotyping. And finding the Spacer gate was pretty interesting, though also a series of incredible coincidences. It definitely added some suspense to the end of the chapter, and I completely agree with Alex telling them not to open it. But I suppose Midas is going to come through anyway?

Any questions for me?
