Oona Out of Order by Margarita Montimore

It's 1982 and nineteen-year-old Oona is deciding whether to go to the London School of Economics or on tour with the band she's in with her boyfriend, Dale. However, on New Year's Eve, Oona faints and wakes up in 2015 in her fifty-one year old body, but feeling like she's still nineteen, with those years' memories. While Oona is stunned, her personal assistant, Kenzie, and her mother, Madeleine, explain that every New Year's Eve, Oona jumps backwards or forwards in time to a different year. Through Oona Out of Order, the reader is with Oona in many different decades of her life and gets to see both the highs and lows. It's a clever and entertaining page turner.
