Definitely Maybe Not a Detective (2026)
(Wyatt Investigations Mysteries, book 1)
Sarah Fox
"Who hasn't thought of solving murders in their spare time if given the chance? Okay, not Emersyn Gray, but when a handsome man, a fake detective agency and a body drop into her life at the same time, what's a girl to do? Fast-paced and quippy, Definitely Maybe Not a Detective is sure to please fans of the Finlay Donovan series."

The Marigold Cottages Murder Collective (2025)
(Marigold Cottages, book 1)
Jo Nichols
"The residents of Marigold Court have one, small problem--a dead body was found in a hedge and one of the residents is accused of killing him. Nothing brings a disparate group of people together like a murder! They decide to unite to solve the case and hopefully save the property from the shady land developer who wants to tear down their community. Not in their backyard! By turns funny, smart, and cozy, fans of Agatha Christie and Kat Ailes will whip through this one."
