For fans of Brick or Paper Towns comes At the End of Your Tether, the story of a boy who goes searching for his missing ex-girlfriend only to discover that some things aren't meant to be found. It's a humid summer night in August 1997 and Ludo Carre is nervous. He hasn't seen or spoken to his ex, Arlo Quinonez since he was fifteen. Now, he's returning home to be reunited with the one person he made a connection with in his youth. The night before he arrives, Ludo gives her a phone call. Big laughs and a familiar cadence in Arlo's voice don't just instantly calm him down -- they make him excited to see her. That excitement only hurts him more when they show up the next day and find out Arlo has been missing...for the last week. Determined to find her, Ludo takes things into his own hands, but the further he gets into his investigation, the more he questions how well everyone on base, in town, and even he himself really knew her. Gone without a trace, the girl he once knew everything about has now become a mystery. Where is his best friend -- and who is she, as well?
