Sixteen-year-old Kiva Fariq has always dreamed of soaring on the four-winged raptors that scour the desert skies. But the windwalker sect is closed off to women. What's more, it's said the deadly predators can only be bonded by men.

Undeterred, Kiva attempts the deadly windwalker trials in secret. Should she survive, she will face an even greater challenge: bonding a raptor of her own. When signs of an ancient enemy appear upon the plains, she desires more than ever to protect her people. But the threat is closer than anyone realizes, and will soon bury them all in a tomb of sand and stone—unless she can stop it.
