Last summer, Sadie Vale walked away from the Sea Glass Festival bonfire at 11:10 p.m. Nobody has seen her since. They found one sandal on the rocks below the old lighthouse. They found her diary. They decided her boyfriend did it.
This summer you're seventeen, the new girl, washing dishes at your aunt's inn on Halcyon Island. On your first night, someone leaves a piece of blue sea glass on your pillow, wrapped in a note in Sadie's handwriting.
"THEY'RE ALL LYING."
"START WHERE THE LIGHT USED TO BE."
THE ANNIVERSARY BONFIRE IS IN SEVEN DAYS.
A podcaster who made Sadie famous. A boy the whole country thinks is a murderer. A girl who knows every back door on the island. A father who smiles with all his teeth. Everyone is hiding something. Somebody is watching you.
