If you got away with murder, would you spend your final moments confessing your sins or let the truth die with you? At just forty-one years old, Rachel Marless is given months to live. After accepting the devastating news, she makes a decision: She will spend her final days imparting wisdom, advice, and confessing a long list of misdeeds to her only niece, Linnea. Linnea is a freshman in college and can't believe she's losing her favorite aunt before they've had time to travel the world together. From the moment she receives the news of her aunt's diagnosis, Linnea vows to spend each Tuesday afternoon with Rachel. Every week, she listens to her aunt's stories and learns devastating secrets about the woman she thought she knew better than anyone. Aunt Rachel has done awful, unspeakable things in her life, but nothing will be as bad as her final confession. Can Linnea handle the truth, and will Rachel live long enough to tell it all?
