SPONTANEOUS (4) by Brenda Jackson: Ex-cop turned P.I. Duan Jeffries has shared an attraction with ER nurse Kimani Cannon for a while, but they haven't explored it. That changes when Duan's brother marries her best friend and Duan and Kim have sex during the wedding reception. As they get closer, Duan learns Kim's mother's fiance is a man he once suspected of murdering his first two wives. It's game on as Duan tries to catch a criminal while romancing Kim -- who's more focused on her career than on love -- and coming to terms with his own issues with matrimony. A fast-moving, intrigue-laced plot and plenty of sizzling sex keep the reader turning pages. A great read indeed.
