Led by Her Heart. A Lynn Callahan Romantic Suspense, #1

Lynn Callahan, a divorced single mom with her own party planning business, is content in her busy life until her ex husband, Drew, fails to pick up their seven-year-old son from school. Because Drew is a recovering drug addict, the police don't believe he's missing, he's probably off on a bender somewhere, but she knows he wouldn't relapse after eight clean years, so she hires a private investigator to take on the case.
While helping Jake Connolly, she's thrust into a life of mystery, drama, action, and romance. After Drew is found, her job becomes mundane, and she misses the excitement of working with Jake, but becoming a PI herself seems impossible, even with his help. However, when a young boy goes missing and a murder suspect is wrongly accused, despite the obstacles and risks, she must abandon all doubt and let her heart lead her to adventure, love, and true happiness.
