A teen girl competes in an illegal scavenger hunt for a life-changing cash prize, but when a boy ends up dead, she has to unravel what really happened that night. For fans of The Inheritance Games and A Good Girl’s Guide to Murder.

When 17-year-old Madison Mercer hears the local sheriff is investigating a tip about a body in an abandoned car in the woods, she’s not sure what’s more horrifying: that someone found the car, or that it was empty.

Because Maddy knows there was a body in the trunk.

That’s where she stashed it.

The previous summer, after a season of losses – her mother passing, her family’s diner closing, her best friend moving away, her father slipping into alcoholism – Maddy decides to participate in the Lark. The wholly illegal annual scavenger hunt takes teenagers through woods thick with illegal weed grows, down abandoned train tunnels, and into locked houses. The prize this final year is bigger than all the years combined: a whopping $100,000. The money would be the only thing to keep Maddy and her family slipping further into poverty, so she’s determined to win at any cost.

But when a boy ends up dead, Maddy knows she needs to find the killer… or risk being implicated herself. As she tries to unravel what really happened, she realizes that the game never truly ended. Because in the Lark, there’s only one rule: Trust no one in the dark.
