Every morning at 6:20, the former captain of a paratrooper regiment, Travis Devine, headed to Manhattan to work as a financial analyst. He followed the news and prepared for his workday. But his ordinary life changed when he received an anonymous message about the death of Sara Yus, his ex-lover. He learned that her death was ruled a suicide, but he didn’t believe it. He is convinced she was murdered, and now he’s trying to figure out why he was told and who could have caused her death.
