Really enjoyed this sweet, thoughtful, nostalgic YA book! Yes, even though the author markets this as her first adult book, I’d say this is the definition of YA—emotional, full of the energy and anxiety and anticipation and plot twists of youth—with a perspective of the adults in the future who are still young at heart. What have we learned? You can’t change the past. Every moment of your life is real, every day counts. You can’t predict the future. As a college student, I ran a literary magazine, so this cast and setting spoke to my past and filled my memory bank and made me wonder where all my friends ended up twenty five years later! Why the 3.5 stars? The time travel stuff was amusing but felt shallow, in the end—and I think I’m skeptical that adults would behave like such children for such a long time.
