The Ex Who Wouldn’t Die (Charley’s Ghost Book 1) by Sally Berneathy

When Amanda’s lying, cheating, scam-artist husband, Charley, saves her life in a near-fatal motorcycle accident, she can almost forgive him for dragging his feet on their divorce. Then she discovers he’d been dead for several hours at the time she thought he rescued her. And not just dead…murdered. On the good side, at least they are no longer married. But she’s the primary suspect in Charley’s murder and, as if that isn’t bad enough, Charley’s ghost shows up in her apartment. He was rejected, kicked back, not allowed to go into the light. The situation was bad enough when he was alive and trying to charm his way back into her life, but now he claims to be unable to go more than a few yards away from her. Even death did not them part.
