Revisiting Corus is normally a series of posts reviewing the books set in the Tortall universe. However, Tortall: A Spy’s Guide just came out on October 31st, so we’ll be interrupting our scheduled posts to review it!
I didn’t really know what to expect going into this; all of the pithy online descriptions call it “a great gift for Tortall fans!” Which gives the impression that it’s more of a fanbook than a book, without anything new to offer. It’s also presented in a library binding style (cover printed directly onto a hardback surface), which is generally done with these sorts of ancillary books. These types of books have become popular: There’s Percy Jackson and the Olympians: The Ultimate Guide, The TARDIS Handbook and Sherlock: The Casebook, among many, many others. These books are generally smaller and cheaper than art books or making-of chronicles, and are written in-universe, with characters compiling files for one reason or another.
