Tommy and Ozzie have been best friends since second grade, and boyfriends since eighth. They spent coutless days dreaming of escaping their small town—and then Tommy vanished. More accurately, he ceased to exist, erased from the minds and memories of everyone who knew him. Everyone except Ozzie. Ozzie doesn't know how to navigate life without Tommy and soon suspects that sowethung is going on—that the universe is shrinking. When Ozzie is paired up with the reclusive and secrative Calvin for a physics project, it's hard for him to deny the feelings that develop between them, even if he still loves Tommy. But Ozzie knows there isnt much time left to find Tommy—that once the door closes, it can't be opened again. And he is determined to keep it open as long as possible.
