Guardians have patrolled the Umbral gates for centuries, defending unsuspecting humans from the body-craving Lurkers within.

However, as an ancient stewardship passed down through family bloodlines, it is time for a new Apprentice to be chosen.

And it’s Moriarty’s worst nightmare.

Moriarty has reluctantly wielded the Guardian’s Scythe for seven years, determined to make sure the bloodline inheritance ends with him. 

But he can’t control the march of destiny.

The mantle of Apprentice Guardian inevitably falls upon his two-year-old niece, Dessa, and an eldritch Lurker awakens to hunt her.

Can Moriarty bring himself to help Dessa develop the power she needs to fight back? And can he keep her alive long enough to wield the Scythe as the next Guardian of the Umbra?
