Grace and Tom are about to face their most challenging mission so far? Bestselling author Vashti Hardy returns with a heartfelt and action-filled third addition to the Griffin Gate series.

Grace’s family are wardens of the Griffin map, using its teleport technology to fight crime across Moreland. And now there’s someone new on the team: Tom Eely, who has been training hard to become a warden.

Grace and Tom reckon they’re ready to tackle a mission together, but they’re disappointed when Mum sends them to a quiet mountain village where ravens have been pestering the locals. Surely they won’t be any opportunities to use their exciting gadgets or combat skills there?

But as the pair investigate, the situation becomes more puzzling. Why does it seem like the ravens are protecting something? And are the villagers’ tales of a mountain witch really to be believed? Grace and Tom will have to use all their wit, skill and courage if they want to solve the raven riddle ?

Particularly suitable for readers aged 9+ with a reading age of 8.
