Cassandra Hale has been called desperate, volatile, and pathetic—the wife who clings too hard to a husband who stopped loving her years ago. But the night she finally plans to let go and tell David about her terminal diagnosis over a carefully prepared dinner, he walks in at midnight reeking of perfume, ready to serve her divorce papers. He's been having an affair with his assistant for six months, she's pregnant, and he's already drained their accounts and planned his escape. When David dismisses her stage four cancer as another manipulation tactic, Cassie realizes she's been playing the wrong role in their marriage all along. Now, with six months left to live and nothing left to lose, she's done being the woman everyone pitied—and David is about to discover that a dying woman can be far more dangerous than a desperate one.
