Mr. Penumbra's 24-Hour Bookstore
by Robin Sloan
My rating: 5 of 5 stars
This book was funny, it was charming, it included a quest, ancient books, historical info on typography, lots of computing power, and a dungeon master. What more could you want from a book? Also, the ending was perfect for the story.
"A man walking fast down a dark lonely street. Quick steps and hard breathing, all wonder and need. A bell above a door and the tinkle it makes. A clerk and a ladder and warm golden light, and then: the right book exactly, at exactly the right time." (p. 288)
If you want a second opinion, check out the Indextrious Reader's review which also includes a very cool reading map.
