The Isle of Faerie is a terrible, glorious, wonderful land. The air is warm, the flowers sweet-smelling… and time no longer means quite what you thought it did. There are broken limbs on the grass, and the rivers want to drown you.
Rinaldo Device is stranded in a world where his magic of metal-working means nothing. Without his brother. Without a way home. And the worst secret he's ever kept is about to come spilling out…
Back in London, Flavia and Orlando hurry to put a rescue plan together for Rinaldo and the Gloucester children, but they may already be too late. The Queen of Faerie is out for revenge, and no one can stand in her way. Not even an angry princess, a heartbroken daughter, or a mysterious yellow cat.
