Every soul in the country is bound by a thread to the Loom, the world engine kept by the Order, and no one feels the cord, the way a fish does not feel water. Adam is Threadless, unbound, and Book One is the warm, patient story of what a home is: a village kitchen with the door latched and a big working dog named Raa asleep on the threshold, until the Order's rider burns the warmth to the ground.

Adam, Lira and Kyle are taken for what they are, and inside Greyspire each is found to carry something far older than themselves. Adam carries Mada, the void. Lira carries Hazina, the god of endings. Kyle carries Kaleb, who judges debts. From captivity to escape, from breaking the Order to killing gods, their story climbs to a single unbearable choice: destroying the machine saves the world and exposes it to the older dark it was built to hide it from.
