In the House of Root and Rot (The Altered Planes)

The dead don't stay silent.

Old Gramps always said the Deadmarsh family was cursed. Will never believed him—until now.

In a last-ditch effort to pay his grandfather’s mounting medical bills, Will signs up for a shady sleep study, ignoring the warning signs. But everything changes the night his grandfather vanishes. In his place, Will’s dead sister returns.

Convinced the sleep study is to blame, Will tracks down Spectre, the enigmatic research firm behind it, only to discover they’ve disappeared. His search leads him to a girl whose father vanished after her own harrowing encounter with Spectre. She also seems to know more about his family’s past than she’s letting on.

Desperate to stop seeing his dead sister and unsure of who to trust, Will forms an uneasy alliance with the girl to find out what Spectre wants with them. Together, they plummet down a rabbit-hole of secrets, discovering Spectre’s true purpose and what it planted in Will’s bloodline centuries ago. Something ancient, something not of this world, has been feeding off his family for generations, growing stronger, hungrier, and desperate to be set free.

The family curse is real. And it’s been waiting for Will to unleash it.
