A girl goes missing in Bellhaven, New Hampshire. A cop goes looking.
Officer Wren Whitmore has spent twelve years quietly rebuilding her life around the absence of her sister Lily, who vanished at seventeen on a stretch of road outside town and was never found. She is good at her job. She is not good at much else.
When sixteen-year-old Chloe Decker disappears in October, Wren recognizes something in the case she can't name - not yet. A trusted mentor. An older man. A girl who felt, for the first time, truly seen.
In a town that prefers comfortable explanations, Wren is about to ask the most dangerous question of all: what if the person everyone trusts most is the one nobody should?
26 Marks is a literary thriller about grief, institutional failure, and the cost of silence - for readers of Tana French and Gillian Flynn.
