Return to the fascinating world of Harmony where deadly energy ghosts lurk in the ruins of an ancient alien civilization; where dust bunnies prove to be loyal pets and where a ghost hunter will discover that a woman's heart is the most dangerous adversary of all...

Local Guild boss and powerful ghost-hunter Cooper Boone is everything botanist Elly St. Clair could ask for—the handsome, strong and silent type. Maybe too silent. For when Guild secrets threaten her career at the college, Elly has to call of their marriage—and leave small-town life behind.

But starting over in the thriving metropolis of Cadence City isn't easy, especially when one of Elly's new friends disappears in the eerie catacombs beneath the streets. Elly sets out to investigate with her new pet dust-bunny, Rose (who is very fond of jewelry). But there's a serious complication. Cooper Boone has just arrived in town. He's there to claim his runaway fiancé.
