Some memories are lost for a reason. Others are taken.
Theo's about to find out which kind he's missing.
As more notes follow, each more intimate and disturbing than the last, Theo finds himself drawn into an unraveling mystery that seems to reach beyond the limits of memory itself. With the help of a classmate who may know more than she's letting on, and haunted by dreams of a greenhouse that doesn't exist, Theo must uncover the truth behind the messages-and the missing boy named Julian who might be the key to it all.
But the closer he gets, the more the edges blur between the past and present, between what's real and what should never have been forgotten.
Perfect for fans of A.S. King, Adam Silvera, and We Were Liars, You Were Here Once is a psychologically rich coming-of-age mystery about loss, love, and the haunting power of memory.
