The Inexplicable Logic of My Life by Benjamin Alire Saenz

A "mesmerizing, poetic exploration of family, friendship, love and loss" from the acclaimed author of Aristotle and Dante Discover the Secrets of the Universe. ( New York Times Book Review)
Sal used to know his place with his adoptive gay father, their loving Mexican American family, and his best friend, Samantha. But it's senior year, and suddenly Sal is throwing punches, questioning everything, and realizing he no longer knows himself. If Sal's not who he thought he was, who is he?
This humor-infused, warmly humane look at universal questions of belonging is a triumph.
