"If you read just one book this year, read this one--a time-bending love story full of nostalgia and 'what-ifs.'"--Sophie Cousens, New York Times bestselling author of Just Haven't Met You Yet "A grown-up love story that captures the beauty of not only finding your person but holding on to them. Throw in some time travel, great music, and '90s nostalgia, and you have an unforgettable read."--Laurie Gilmore, #1 New York Times bestselling author Meet Adam and Jules. Married for nearly twenty-five years and stuck in a rut, their future looks, well, boring. Then Adam stumbles across a box of old mixtapes he and Jules made for each other when they were young and falling in love. He dusts off his vintage stereo, inserts one of the cassettes, presses "Play" ...and the unbelievable happens. With the power to travel back in time, Jules and Adam can recapture the headiness of falling in love. But they soon realize that visiting the past could be as dangerous as it is addictive, because the temptation to change just a few tiny things is irresistible. As the consequences start to spiral out of control, can they find a way back to their messy and imperfect, yet glorious, real life? Or will they lose each other forever?
