"Most people I know live their lives moving in a constant forward direction, the whole time looking backward." In this book, a time travel machine technician goes between universes saving people from (ab)using time travel in their efforts to fix their disappointing lives. When he's not doing that, he's searching for his missing father, who disappeared after inventing time travel. Within this strange and mind-bending plot, Yu addresses some of life's most philosophical questions. Is time a forward trajectory? Do regret and nostalgia serve us? How do we reconcile with the ache of a parent's lost dream? This book is an unconventional but beautiful tribute from a son to his father, and calls on us to reimagine the way we think about time.
