Mr Penumbra’s 24 Hour Bookstore

Oops. I forgot to blog Mr Penumbra’s 24 Hour Bookstore. I finished it before Christmas. Before the kids arrived. Hmmm the 19th? The 18th? Something like that.

I read it really quick — almost couldn’t put it down. Mysterious bookstore in San Francisco — lots of geeky google stuff, silicon valley, codebreaking, social media, libraries, cool stuff like that. I really had fun with this one.
