The Devil’s Workshop Series by K. Simpson

Devlin Kerry is the reluctant creative director in charge of sex at an ad agency. Never mind that she’s been celibate for six years–for which she’s being haunted by her own personal demon, Monica. Best friend Cassie has dedicated herself to making Dev’s life a living hell and, as luck would have it, is the only person who can checkmate Monica. Can Devlin endure all this devilish havoc and still survive the agency’s infamous Halloween party? The Devil’s Workshop, Book 1

Devlin Kerry isn’t your average associate creative director in charge of sex. Not only does her personal demon, Monica, turn the ad agency’s Halloween bash into her coming-out party, but now she has to deal with her best friend Cassie’s demon, Vanessa. Consider this a warning against mixing sex, advertising, and demons: One is bad, two is worse, and three is the state of Dev’s life. The Devil’s Workshop, Book 2

Devlin Kerry and Cassandra Wolfe lead very complicated lives. They’re in advertising, they’re a couple, and they each have a personal demon. They decide to cap off a perfectly hellish year by spending Thanksgiving with the Wolfes and Christmas with the Kerrys. Between their crazy demons and even crazier families, Dev and Cassie are reminded that there’s no place like hell, um, home for the holidays. The Devil’s Workshop, Book 3

Put Devlin and Cassie, their demons, New Orleans, and voodoo together, and what do you get? Just more devilish fun from our favorite possessed ad executives. Also, Dev and Cassie try to answer that great eternal question: How do you spend an anniversary that happens to be on Halloween without your demons and most of the spirit world playing havoc with your plans?
