Book excerpt: It's Kind of a Funny Story meets Turtles All the Way Down in this harrowing yet hopeful account of a teen living with Tourette syndrome and obsessive-compulsive disorder while contemplating his own mortality. Ten: three little letters, one ordinary number. For Troy Hayes, a 16-year-old suffering from Tourette syndrome and obsessive-compulsive disorder, the number ten dictates his life, forcing him to do everything by its exacting rhythm. Fed up with the humiliation, loneliness, and physical pain, Troy creates a list of ten things to do by the tenth anniversary of his diagnosis--culminating in suicide. But the process of working his way through the list changes Troy. He becomes friends with Khory, who unwittingly helps Troy cross off items on his list, even as she shows him that life may have more possibilities than he imagined.
