Jealousy’s a Witch by Louisa West

She thought the thriller part of her life was behind her. But when the man she’s falling for has a sinister secret, she’s no longer sure whether he’s a trick or a treat.

Rosemary Bell is a witch for Halloween… and every other day of the year. And that’s not even the weirdest thing about her life. Her ex-husband is a turtle, her daughter Maggie’s new best friend is an imaginary kangaroo, and the guy sleeping on her couch is a King—as well as her fated lover.
Just as she’s starting to fall for Declan, Rosie gets spooked by a revelation that leaves her wondering whether she is really meant to be his Queen. And as a new houseguest quickly proves, promises don’t always mean forever. When a sexy choir girl arrives in town with her eyes set on Rosie’s King and crown, she will have to decide for herself what her destiny is, and soon.
Struggling between caring for Declan and caring for herself, Rosie has better luck advising her friends what to do about their love lives than tending to her own. But when Maggie goes missing on All Hallow’s Eve, Rosie is forced to admit that jealousy’s a witch – literally!
The Good Witch meets Hocus Pocus in this short novel about stepping into new shoes, choosing who you’re going to be, and never letting fear decide your fate, even on Halloween.
