An entire herd of greywyrmes, slaughtered for their flameoil. Others trapped, then viciously herded through the mountains. And more and more settlers heading up to the high country, the bones of those who don’t make it littering the way, stark and white, picked clean by carrionwyrmes – the bone trail . . . Trouble is brewing on the weald. A great whitewyrme and his kin send out a call to arms, and the wyrmes begin to gather in their ancient galleries. To defend their land against the relentless march of the kith, with their wagons and settlements and taste for killing. Payback is coming. Wyrme against kith. Kith against kin. Even wyrme against wyrme. And seasoned traveller Micah, with his friends Eli and Cara, is heading right into the thick of it . . .
