I recently read the wonderful ‘Mr Penumbra’s 24 Hour Bookstore‘ by Robin Sloan. This is a fantastic book that weaves together the worlds of old books and 21st Century technology. Although it is written for a slightly older audience than my Bella Street books, there are a couple of things both have in common — a love of Dashiell Hammett and computer geeks! (you probably can’t say that about too many other books!) Thanks to The Economist for putting me onto Mr Sloan’s great book!
