Taking place seven years after the original Septimus Heap series, this first book in the TodHunter Moon trilogy tells the story of Alice TodHunter Moon, a young PathFinder who leaves her seaside village in search of her friend Ferdie. Rumor has it that Ferdie has been taken by mysterious creatures called Garmin under orders from the malevolent Lady.

Full of Angie Sage's characteristic humor and heart, and with appearances from the beloved Septimus Heap gang, this spin-off series introduces new young heroes and scenery—and a new kind of Magyk, too.
