'The Bone Thief is a riveting mystery with a plot that seamlessly blends history with fiction. And Syd Walker is an unforgettable protagonist.'
—Liz Moore, New York Times bestselling author of The God of the Woods

Washington Post ‘Best Mystery Novel’ of 2025

When a Native teenager vanishes from her small town—a place with dark ties to an elite historical society—archaeologist Syd Walker is called to investigate...from bestselling author Vanessa Lillie.

In the hours before dawn at a local summer camp, Bureau of Indian Affairs archaeologist Syd Walker receives an alarming call: newly discovered skeletal remains have been stolen. Not only have bones gone missing, but a Native teen girl has disappeared near the camp, and law enforcement dismisses her family's fears.

As Syd investigates both crimes, she's drawn into a world of privileged campers and their wealthy parents—most of them members of the Founders Society, an exclusive club whose members trace their lineage to the first colonists and claim ancestral rights to the land, despite fierce objections from the local tribal community. And it's not the first time something—or someone—has gone missing from the camp.

The deeper Syd digs, the more she realizes these aren't isolated incidents. A pattern of disappearances stretches back generations, all leading to the Founders Society's doorstep. But exposing the truth means confronting not just the town's most powerful families, but also a legacy of violence that refuses to stay buried.

From the national bestselling author of Blood Sisters (a Washington Post Best Mystery of the Year and Target Book Club pick) comes a new Syd Walker novel that proves the sins of the past are destined to repeat until the truth is finally unearthed.
