Mr Penumbra's 24-hour bookstore - Robin Sloan

I took this book with me on a travel to my parents who live on the other side of the country,which is over here,three hours by train.
A book with Google and the internet. Strange as it may sound considering this book, it felt like the real world. I must not have read a book grounded in this century for ages!
I think I read all books refferenced so far (okay, not the visual display of quantative information), which makes me happy being ecclectic.
