Meet Toby, the super-bright, skinny Asian guy and his feisty, red-haired sister Rita. Throw in Carl, his brain addled by ADHD and any substance he can lay his hands on. And Don, son of alcoholic parents whose actions one fateful night change the path of all their lives. As Toby finds himself deep in trouble and confused about the truth, he is forced to the vital question: are we really just puppets controlled by our genes, or do we have the free will to rewrite our own destiny? Suggested level: secondary.
