Ben’s world is changed when a very demanding little cat named Iggy begs Ben to free him from the evil Mr Dodds’s Pet Emporium. Iggy, it seems, hails from the magical world of Eidolon, where Dodds – known in Eidolon as the Dodman, a terrifying monster with the head of a vicious dog – has been kidnapping magical creatures to sell as exotic pets in England. Worse, Ben’s own mother is Eidolon’s rightful queen, and as magic is siphoned from the land by the Dodman’s cruel trade, Ben’s mother grows steadily sicker. Her only hope – and Eidolon’s – is for her to return to Eidolon, stop the Dodman, and reclaim her birthright. But though Ben and his sisters are the prophesied saviors of Eidolon, can they really defeat the Dodman and the various monsters he has gathered against them?
