This is a romantic memoir of sorts, written by Oliver Sacks late-in-life boyfriend. (Now I want to read HIS memoir.) It’s told in fragments, but more or less chronologically, flipping between encounters the author has with the people of NYC, and fragments of his journals that are mostly filled with his life with Oliver. (They end up living in separate apartments in the same building, because they met when Sacks was over 70 and he was a little too set in his ways.) But the things he says! Hayes captures Sacks as this brilliant genius with a completely guileless soul. And the fact that he embarks on this relationship with Sacks after his previous long-term boyfriend passed away suddenly . . . this book is just beautiful. Just . . . WOW.
