This is one of those books that is written in a very commercial, easy to digest manner, which allows the book not to feel like a big brick of 600 plus pages.
The story follows a teen with Asperger's, and how that changes the whole fanily dynamic: absent father, mom that sacrifices everything to accomodate for her son, younger brother that has to play older brother and feels neglected. 
Jacob can sound like a genius about a few things, but lacks other basic skills communicating, understanding metaphors, recognizing facial and body language. Everything is planned and scheduled to the minute. Any disruption makes him have a meltdown. If all this is challenging on a normal day, imagine when he has to sit in court accused of having commited murder.
The story is very informative about Asperger's, although some things sound outdated. Also, we get to learn a few things here and there about forensic investigation, and who doesn't love a good old session in court. Objection!
The story is well told, and I liked the different points of views, as they allow us to see how Jacob sees the world, how Emma, the mom, feels overwhelmed and guilty, and sacrifices everything, Theo, the brother feeling neglected and craving for a taste of a normal life in a normal house. And also how people from outside, like Oliver and the detective, see Jacob and are quick to judge.
What bothered me about the story was the males drooling all over Emma, and even the relationship that ensues at some point. Totally unnecessary, I don't need these Wallmark-y things.
The book ends abruptly, we don't get to see the outcome of the trial and the afterwards, but from Jacob's point of mind all was clear from the start, so why bother?
