This is one of those books where I feel like I have to draw a firm distinction between "books I think are really good" and "books I really like." I think this book is really pretty brilliant, even though it wasn't totally to my personal taste. It's a crazy-smart-unusual take on the notion of time travel, but it left me a little cold. Also, time travel is not my very favorite thing in the world, though it's not a deal-breaker for me. 
 All in all, I will be strongly recommending The First Fifteen Lives of Harry August to certain friends, though I will probably never reread it myself.
