Lies She Told by Cate Holahan

Sometimes the truth is darker than fiction.

Liza Jones has thirty days to write the thriller that could put her back on the bestseller list. In the meantime, she’s struggling to start a family with her husband, who is distracted by the disappearance of his best friend, Nick. With stresses weighing down in both her professional and her personal life, Liza escapes into writing her latest heroine.

Beth is a new mother who suspects her husband is cheating on her while she’s home alone providing for their newborn. Angry and betrayed, Beth sets out to catch him in the act and make him pay for shattering the illusion of their perfect life. But before she realizes it, she’s tossing the body of her husband’s mistress into the river.

Then the lines between fiction and reality begin to blur. Nick’s body is dragged from the Hudson and Liza’s husband is arrested for his murder. Before her deadline is up, Liza will have to face up to the truths about the people around her, including herself. If she doesn’t, the end of her heroine’s story could be the end of her own.
