When Julian Gibson realizes he's transgender, he doesn't think anything has to change. His parents and friends still call him Julia and think he's a girl, but so long as Julian can still hang out with his best friend Aiden and read sci-fi novels with his dad, life seems pretty good. Then high school happens. Aiden ditches him, and a new girl, Maria, keeps cornering him in the girls' bathroom. A full year after discovering he's transgender, Julian realizes life changes whether you're ready for it or not. So Julian makes a deal with himself: if he can tell his secret to three people, it is no longer a hoax. What happens during his slow process of coming out leads Julian down odd pathways of friendship, romance, Christmas shopping, random parties, bad movies, and a realization about why kids still believe in Santa -- it's sometimes better than discovering the truth.
