Molly: Book 1 of Thriller Series

Sarah Hartley is a single mother living in a small Midwestern town. Her son, Tommy, is the best part of her. She loves him dearly and works to give him everything she never had growing up. One day when picking Tommy up at his daycare, she encounters a woman she's never seen before. The woman, Molly, is seemingly nice and friendly, but when a problem with her son finds her at the receiving end of a 'Mom-zilla's' wrath, Sarah must stand up for her. The two women stick together and become good friends. 

One day in a park Molly confesses her past to Sarah, and it only brings them closer. Soon they are sharing life's struggles and evening out the weight of being single mothers. Is this the beginning of a lifelong friendship? It sure looked like it. But Molly’s increasingly unpredictable behavior makes Sarah question her motives and wonder who she’s really dealing with.
