How Great Thou Art by Michele Bardsley

When werecougar Caulder Mason loses Art Cobbler, his sister’s vampire buddy from the Adopt-an-Elderly-Vampire program in Broken Heart, his search leads him to the newly formed paranormal town of Lost Souls, Arkansas.

Fae-demon Lavender Greengrass moved to Lost Souls because venturing into the world usually means destroying some part of it. Not on purpose. Her demon side just … well, leaks out every now and again. But when an elderly vampire appears in her backyard—on fire—she has to help. And when the handsome werecougar shows up on her front door looking for Art, she can’t turn him away, either.

Then her jerkface demon cousin, Ferth, kidnaps her grandmother and Art, and suddenly, she and Caulder must combines forces to save the day—er, elderly. Sometimes, two people are just meant to be together, even if they have to go to hell (they do), to prove to each other that true love can conquer all.
