Grave Inn-tervention by Aurelia Skye

Wedding bells are ringing, and The Entity is in stealth mode.
Meredith and Hunter are about to get married when she can no longer feel the Entity. It’s frightening, but they have to keep living. They take a brief honeymoon and meet a new ghost before Brett frantically calls them back. The Entity has taken Chayse.
Meredith has no choice but to face off with The Entity now. With old friends and new allies, maybe they stand a chance against the Entity. Maybe.
Or maybe they’ll all be trapped inside Purgatory forever. It could go either way.

This novella wraps up Meredith’s arc, though it’s possible new adventures might await her in the future.
