Three years ago, Carson's sister ran away. Now he's found her--on a porn site. High-school senior Carson Banks is trying to find out what he wants to do with his life, wanting to move forward, though a part of him is firmly rooted in the day his life changed forever. The day his older sister Caitlin ran away, and disappeared without a trace. Then, he finds her--on an Internet porn site. Deciding that finding Caitlin and bringing her home is the only thing he can do, Carson embarks on a quest that ends up changing him as much as Caitlin seems to have changed herself. Coping with the knowledge that he can't share with the rest of his family--yet--Carson writes thinly veiled autobiographical stories to help himself better understand Caitlin and why she left home. And, while using every opportunity he has to find Caitlin and talk to her, Carson's typical teenage life goes on. Girlfriend. Family. School. Friends. Things he did in the past that he's not too proud of. It's a busy senior year, but he'll count it a win--if he can locate her, learn exactly what happened on the day she left and convince Caitlin to come home.
