In Book Three of the Silver Sequence, the Roar descends upon Coldharbour, where millions of children huddle in search of protection.
Milo, the silver child, is the first line of Earth's defense. Under his wings, Helen probes the Roar's mind with her gift of telepathy, searching for a weakness. The twins at last free the mysterious Protector from the ocean floor, while Walter strives to keep everyone alive while they search for a weapon that will destroy the Roar. Only Thomas can release that weapon―if he can finally discover the true purpose of his remarkable gift.
Meanwhile, from Earth's inner core, Carnac, the Roar's firstborn, begins to emerge. Only Tanni and the Unearthers stand in his way...
