With Casey reunited with Matt and the rest of her friends, they put together a plan of attack to take down Walker and the Nest once and for all. In order to win the war, and their freedom, the Chosen Ones must battle genetically made half wolf, half human hybrids, an army of ex-military guards, and a new horrifying experiment created in the Nest's laboratory. They must do this with the goal of keeping Tyler safe from Walker, who will do anything to get his hands on the boy and harness his powers all for himself. This is book 3 in the Chosen Ones series. Look for Book 4: A New Enemy.
