Mr. Penumbra's 24-Hour Bookstore

A twentysomething website designer suddenly finds himself without a job and takes a job at the titular bookstore. He quickly learns that the odd bookstore has even odder books and few (and secretive) customers. So he investigates what's going and brings in some friends into the investigations and they lead to a secret society. There's a lot of cool ideas going on here and so many geek and pop-culture references that it helps to be familiar with Generation X stuff. But while the story drew me in immediately, once I was halfway through it wasn't as much as a page-turner as before. Also, the characters are basically ciphers. But it was interesting enough to finish it. One thing is for sure, the author is a big fan of books, the internet, and Google.
