On the eve of her fortieth birthday, Alice's life isn't terrible. She likes her job, she's happy with her apartment, her romantic status, and her independence, and she adores her lifelong best friend. But something is missing. Her father, the single parent who raised her, is ailing and out of reach. When Alice wakes up the next morning somehow back in 1996, it isn't her sixteen-year-old body that is the biggest shock, or the possibility of romance with her adolescent crush. It's her dad: the vital, charming, forty-nine-year-old version of her father with whom she is reunited. Now armed with a new perspective on her own life and his, is there anything that she should do differently this time around? What would she change, given the chance? With her celebrated humor, insight, and heart, Emma Straub cleverly turns all the traditional time travel tropes on their head and delivers a different kind of love story-about the lifelong, reverberating relationship between a parent and child.
