Chrysta York and Thomas Monroe, against all odds, have survived their ordeal with the acolytes. But as they try to settle into their new way of life, the question remains: what will happen to Chrysta, the first sorcerer to glow gold in centuries, and Tommy, a changeling whose violent history still haunts him? Headmaster Burke has a plan for Chrysta. He wants to transport her into a glass sphere, a powerful magical artifact that will help him train her in isolation but leave them vulnerable to attack. So they will need protection as Chrysta learns to control her new abilities. So as Tommy, hunters, and even the Disaster Club gather together to guard the sphere and keep it safe, dark forces somehow learn of their plans and are looking for them. They will destroy the sphere at any cost and eliminate anyone in their way. Tommy has encountered the generals of the Golden One, her most loyal servants, before. And now he will have to face them again to keep Chrysta safe.
