Last month, the U.S. cover for Garth Nix’s long, long-awaited book, Clariel, finally hit the internet. (That’s it to the left!) For those of you who don’t know, Clariel is a prequel to Nix’s Old Kingdom trilogy, and it may just answer some questions about how the magic in in the series works. Free Magic? The Charter? From the very first page of the very first book, Nix launches his readers into a fully-realized world which he, infuriatingly enough, never fully explains. All the rules appear to be there, and Nix knows all of them—but we don’t. Until now… maybe.
