On a night when the veil between the living and the dead is as thin as a soap bubble, Will McCurty discovers a chilling family legacy.

Each generation's firstborn becomes a medium, a Bridge between the living world and the In Between. It shouldn't affect Will, but his older brother needs a Keeper, someone who can make sure the anguished spirits move on.

Becoming a Keeper means Will must harbor secrets, lie to friends, and break his mother's heart.

It's that or abandon his brother to the desperate dead.
