The Hanged Man's Wife (Marti Keller Mysteries)

Marti Keller was married to the man of her dreams and had a satisfying career as an emergency room nurse. But a soul-shattering tragedy turns her world upside down, leaving her desperately clinging to the one precious thing left in her life. After her search for a work-at-home job leads her to rediscover her long-suppressed ability to communicate with ghosts, she encounters Spam, the restless spirit of a murder victim, who begs her to help bring his killer to justice. She agrees, but her life quickly spirals out of control. Even as she fears she is descending into madness, a mysterious stranger named Quinn steps in to catch her fall. He always seems to turn up just in the nick of time. It’s almost…preternatural. In fact, the more she discovers, the more she finds that everything she thinks she knows is wrong. And that the worst monsters are usually hidden in plain sight.
