Zeb’s life is filled with broken promises, lost homes and loneliness. When he finds himself cornered by a Harpy who promises him his own world in return for a favour, he can’t see much point in saving the current one – particularly when he has a strong suspicion the Harpy will react badly to him saying no.

Zeb is immediately whisked off to Crackle Dawn on the back of a dragon made of bones, where the sun chatters instead of shining and friends appear in the most unlikely of places.
