Klem and Todd are nearly fourteen when the Mangorian army destroys everything they know. Separated from their families and alone in an ancient forest, they are found by the Yukoya — luminous, mouthless beings who sleep inside trees — and given a task that seems impossible: retrieve a green crystal from beneath a dragon’s egg on a mountain nobody can see.
With an unpredictable wizard, a silver marsh-dribbler called Dorky, and a hooded Yukoya venturing into the world for the first time, they travel underground through a golden city, sail into a sea vortex in a turtle shell, and face a Sisterhood who have caged the very dragon they claim to worship.
Above it all, two ancient beings watch from comfortable chairs and try very hard not to interfere.
The luck is real. The light is earned. And the fate of a city under siege depends on two boys from the fens who were never supposed to be heroes.
