Mr. Peunmbra's 24-Hour Bookstore: A Novel by Robin Sloan
Secret codes, old books, Google, and the search for immortality.
Mysterious people in black robes, an underground library with giant books chained to tables, recycled artwork, Google, Warlock role playing, and friendship.
Can Clay solve the code with the help of his friends?
What will Penumbra think?
What will Corvina do?
This is a fun book and a good read!
