I love that Nix‘s Old Kingdom series isn‘t a chronological series but allows him the freedom to bounce around in time. Book 6: Terciel & Elinor jumps some 30 years prior to the birth of Sabriel, the main character of the first book in the series. He also has managed to produce six books in the series that can be read independently of the series and in any order. The creative freedom absolutely shows in each book, a tremendous gift for the reader.
