I like the idea of the story, but so far the delivery leaves a lot to be improved upon. I noticed three major issues with the writing, where you could say two of them are my subjective opinion but the third one is a common mistake coming from not revising the story and is just kind of sad.
1. It is common to switch POV during a story. But that should not happen as frequently as it did here. Using first person narrative helps a lot with making the reader feel closer to the narrator, which is then usually the main character. But getting only a few lines from every character prevents at least me personally from forming a connection with the characters. And if a connection is not established, the first person just feels weird. If you want to switch POV a lot, I suggest trying 3rd person narration. It would feel even more professional then to introduce changes of a scene through writing the place as a sub-heading, instead of the person who's POV is coming next.
2. I noted especially in the last scene, when Aaron tells the boys about Derek's death, that you didn't really add detail to the scenes. I was clearly expecting a description of at least Cam's reaction immediately after he was told of his father's death. Instead you just continued with Aaron talking again. This makes it feel like this whole chapter and tragic death of a person is just a setup to get two (gay) boys that are not genetically related to each other to live in the same house.
There isn't really anything wrong with that and it seams like you invoked some kind of emotion in the other reviewers, but at least for me it was impossible to feel anything there because it happened all way to fast. The dialogue dominated the scenes while I had no clear picture of the scenery or the character's expressions and thus couldn't 'dive into' the story.
3. Please decide which tense you want to write in, and make sure you stay in that time. I know it is easy to slip from past into present, and the way the story is written, with that many POVs, I think present tense might even be more appropriate, but that's entirely your choice. Just make a decision and please give your story at least enough love to reread each chapter before posting and correct tense slips. Or try to find an editor who is willing to proof-read and correct your chapters.
Okay, enough of that. I hope you take this as constructive criticism and don't let this dampen your enjoyment to write. I am not an author myself (yet), but I read a lot and make an effort to notice which features the stories I find the best usually share, which is where my above advice comes from.
I will now go and read the second chapter and I hope you find my review helpful rather than annoying. Anyways please keep up the writing, I want to know where this story goes!
