Amazon offers for sale a complete 12-book boxed collection of the "Ranger's Apprentice" series by John Flanagan. Amazon and other retailers also sell individual books in this collection as well as bundled groupings. For example, readers can buy the first three titles in a single package from Barnes and Noble.
In addition, both Amazon and Barnes and Noble offer Flanagan's second series, "The Brotherband Chronicles." Set in Skandia, the fictional world of the "Ranger's Apprentice," this still-unfinished collection depicts new characters in new adventures on the northern sea. Available in paperback, both of Flanagan's series are published by Random House Australia.
