“An eerie tale offering equal measures of fright, angst, and emotional catharsis.”—Kirkus, starred review

A teenage girl must save her town from a memory-devouring monster in this piercing exploration of grief, trauma, and memory, from the author of The Valley and the Flood.

For generations, a monster called the Memory Eater has lived in the caves of Whistler Beach, Maine, surviving off the unhappy memories of those who want to forget. And for generations, the Harlows have been in charge of keeping her locked up—and keeping her fed.

After her grandmother dies, seventeen-year-old Alana Harlow inherits the family business. But there’s something Alana doesn’t know: the strange gaps in her memory aren’t from an accident. Her memories have been taken—eaten. And with them, she’s lost the knowledge of how to keep the monster contained.

Now the Memory Eater is loose. Alana’s mistake could cost Whistler Beach everything—unless she can figure out how to retrieve her memories and recapture the monster. But as Alana delves deeper into her family’s magic and the history of her town, she discovers a shocking secret at the center of the Harlow family business and learns that tampering with memories always comes at a price.
