Jake Gryphon, tome 3E. G. Foley

« The Pickpocket Who Inherited a Goldmine
After his harsh beginnings as a rough-and-tumble orphan on the streets of London, Jake Everton, the boy Earl of Griffon, takes his rightful place as the long-lost heir of an aristocratic family with magical powers - his personal quest, to follow in his slain parents' footsteps as a Lightrider in the age-old battle of good versus evil. In the fantastical nooks and crannies of the Victorian Age, Jake and his friends (including his pet Gryphon!) find no shortage of adventure - righting magic-related wrongs, solving supernatural mysteries, and exploring wondrous new worlds.

A Dark Presence
Something wicked stalks a quaint town in the misty mountains of Wales, attacking humans and magic folk alike. Jake and his friends must get to the bottom of it - and in the land of deep, dwarven mines, the bottom can be very dark, indeed. »
