What dangers lurk beneath the surface? An uneasy peace has brought about a new era. Sixteen years after their rescue, the half-breeds of the Order have proved themselves to the world and earned their place in society. However, not everyone is at peace within the Order's walls. The children of the Lillies are bound by birth to their destiny-carrying on the bloodline to ensure the future of humanity. While most accept their life of luxury in exchange for their duties, the burden doesn't sit well with everyone. Unhappy children are the least of the Order's problems. Zaddicus, the mastermind behind the Order's disappearance all those years ago, is still at large. His new plans threaten to blow open everything the Surfacers think they know about the world, and this time, he has children of his own.
