Mr. Penumbra's 24-Hour Bookstore by Robin Sloan, 288 pages

My favorite nerdy-librarian genre is books about books and this book delivers.  It's a fast-paced, upbeat, witty, slightly wacky mystery and adventure.  I loved it!

We don't have this book at the library. . . yet.  I borrowed the audiobook via interlibrary loan but we will be adding a print copy soon.

In the meantime, check out Robin Sloan's second book "Sourdough."  We have that book in print and audio already and that's what lead me to Penumbra.
