You’re not suppose to judge a book by it’s cover but I couldn’t resist this book about an unusual book store in San Francisco where patrons show up at odd hours to borrow books. When Clay Jannon is job hunting by foot he sees a help wanted sign at the book store. He is just looking for employment but the owner asks him “What do you seek in these shelves”. When he is hired to work the late shift he must keep a log of all customers, what they wore and what they said. Clay is like his friends reliant on the internet for most things. His girlfriend works at Google and they use the internet to try to solve a puzzle that the patrons who borrow old and strange books have been working on for years. I really enjoyed this story and how the mystery is solved. Not sure why it’s a science fiction novel.
