For 88-year-old Duffy Sinclair, life boils down to one simple thing: maintaining his residence at the idyllic Centennial Assisted Living. So, he keeps his shenanigans to the bare minimum with the help of his straight-laced roommate, Carl Upton. But in this "warm and deeply funny" debut (Booklist), when Carl's granddaughter Josie climbs through their bedroom window with booze on her breath and a black eye, Duffy's faced with trouble that's hard to hide—from Centennial's management and Josie's toxic boyfriend. Before he knows it, he's running a covert operation that includes hitchhiking and barhopping, and the only thing that can save him is an unlikely friendship.
