The Sovereigns (The Sovereigns #4)

Because you demanded it! Tragg and Lorn return, but not even slightly in the place they're supposed to be! Samson's perilous journey across the dead Earth takes a fateful turn, and Magnus prepares to meet his destiny. Oh, and the moon explodes. Also: Doc Spektor, Part 3! The story of the all-new master (and we use the term lightly) sorcerer continues... as Doc clashes with one tough pixie who's come to collect - and then goes Dutch on a date!
