The Borrowed Life of Frederick Fife by Anna Johnston

Frederick Fife was born with an extra helping of kindness in his heart. If he borrowed your car, he’d return it washed with a full tank of gas. The problem is there’s nobody left in Fred’s life to borrow from. At eighty-two, he’s desperately lonely, broke, and on the brink of homelessness. But Fred’s luck changes when, in a bizarre case of mistaken identity, he takes the place of grumpy Bernard Greer at the local nursing home. Now he has warm meals in his belly and a roof over his head—as long as his poker face is in better shape than his prostate and that his look-alike never turns up.

Denise Simms is stuck breathing the same disappointing air again and again. A middle-aged mom and caregiver at Bernard's facility, her crumbling marriage and daughter's health concerns are suffocating her joy for life. Wounded by her two-faced husband, she vows never to let a man deceive her again.

As Fred walks in Bernard’s shoes, he leaves a trail of kindness behind him, fueling Denise's suspicions about his true identity. When unexpected truths are revealed, Fred and Denise rediscover their sense of purpose and learn how to return a broken life to mint condition.

Bittersweet and remarkably perceptive, The Borrowed Life of Frederick Fife is a hilarious, feel-good, clever novel about grief, forgiveness, redemption, and finding family.
