The River Aeon is a literal river of magic, one that confers a new life, immortality, and magical powers onto humans in a package deal called a Concept. The first of these Concepts, a hiker, became the Concept of Thought. They created life, and the City where all Concepts live, safe from the dying world outside.
But in the middle of being human and being a Concept is a limbo, for the Aeon’s magic does not say what the name of the Concept given is, and without the name, a Concept can not grow. One of these Concepts has been in limbo for two thousand years, as long as they can remember, but does not care. Because as a Concept, they don’t have to eat or move, and so can daydream as much as they like—which is for years.
This year, a human called Willow shows up and claims vengeance for wrongs they don’t believe have been committed. She does so by destroying the one thing they love more than their daydreams and stealing their magic, leaving them with weeks to live. And their Concept name is coming for them whether they like it or not, leaving them with more problems.
Will they learn to survive without their magic and daydreams, and avenge their loss? Or will their Concept magic unlock a new path to peace?
