The Monster in the Hollows, Wingfeather Saga Series, Book 3 by Andrew Peterson and published by Hodder Faith.
The kingdom of Anniera has fallen, and the royal family is on the run. Relentlessly pursued by the Fang armies of Gnag the Nameless, Janner and his family hope to find refuge in the last safe place in the world: the Green Hollows – a land of tasty fruits that’s fiercely guarded by warriors feared even by the Fangs of Dang.
But a new problem threatens their hoped-for peace: Janner’s younger brother, Kalmar – heir to the throne of Anniera – has grown a tail. And grey fur. Not to mention two pointed ears and long, dangerous fangs. To the suspicious folk of the Green Hollows, he looks like a monster. But Janner knows better. His brother isn’t as scary as he looks. He’s perfectly harmless. Or is he?
