This wasn't the most captivating book I've ever read, but it was pretty good and I was invested by the end. I definitely learned a good few things about memory from this book, but I have no real experience trying to trick my memory into working better, so who knows. Enjoyable, at least.

Lots of really interesting history of memory and the techniques and science of it.  But the core group of "mental athletes" followed in the modern day is an incredibly sexist, lewd boys club that can be difficult to stomach.   Definitely unlikable characters.
