Mr. Penumbra's 24-Hour Bookstore

“I loved this book as a teenager growing up in SF - just listen to the dust jacket description: “Mr. Penumbra's 24-Hour Bookstore is a 2012 novel by Robin Sloan that blends fantasy, adventure, and technology, following a web designer who takes a night job at a mysterious San Francisco bookstore and uncovers a secret society and a quest for immortality, all while exploring the intersection of old books and new technology”. How fun!! A great read for all.”
