This is a pretty ambitious book that mostly worked (for me). It’s a story about memory in a near future where memory editing and storage is possible. At the center of it is a gay love story and some pretty deep thoughts about what it means to share a life with someone, and how much of that is your memories. Since the book is a lot about the life of the mind, there’s a lot of thinky “in your head” stuff about longing and loss. There are some inception-like “Is this real or is it a simulation? Or a simulation inside a simulation?” bits so if those are dealbreakers, this is not the book for you. Got murky occasionally, mostly great.
