On a night when the veil between the living and the dead is as thin as a soap bubble, sixteen-year-old Will McCurty discovers his dark destiny. In his family, each generation’s firstborn becomes a medium, a Bridge between the living world and the In Between. It won’t affect Will, only his older brother Seth, but to survive, every Bridge needs a Keeper - someone to control the invading spirits, figure out why they’ve come, and help right their wrongs. There’s only one candidate for the job. Will has a choice—walk away from his brother and their shared destiny, or leap into the secret, shadowy world of ghosts and lost souls. Becoming Seth’s 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.
