Pack Up the Moon by Kristan Higgins

Every month, a letter. That’s what Lauren decides to leave her husband when she finds out she’s dying. Each month, she gives Josh a letter containing a task to help him face this first year without her, leading him on a heartrending, beautiful, often humorous journey to find happiness again in this new novel from the New York Times bestselling author Kristan Higgins.

Joshua and Lauren are the perfect couple. Newly married, they’re wildly in love, each on a successful and rewarding career path. Then Lauren is diagnosed with a terminal illness.

As Lauren’s disease progresses, Joshua struggles to make the most of the time he has left with his wife and to come to terms with his future–a future without the only woman he’s ever loved. He’s so consumed with finding a way to avoid the inevitable ending that he never imagines his life after Lauren.
