Theo's family is safe, but the Ten Thousand Worlds are still rife with both danger and opportunity. His old friends are missing, but now Theo's finally caught their trail. For the first time since coming to this strange world of elves and cultivation, Theo must leave the Hearthwood Forest and see the world beyond the trees.

Outside, enemies lurk in wait, eager to tear apart everything Theo has built. But Theo's no longer a wide-eyed and wondrous human. Now, he's got teeth of his own.

Contains mature themes.
