The wise run from them.

Swords are useless against them.

Only the fearless dare pursue them.

Rogue Magick users are the most dangerous people in the world.

When one of them finds a way to become luminous and break into the source of all magick, even their own kind will join the pursuit.

The Render Tracers always say magick users deserve to burn. Aren couldn't agree more, Keluwen would beg to differ, and Corrin couldn't care less either way.

In a world where most people use swords for protection, Aren uses tools that let him see what no one else can see in order to hunt the deadliest people in the world. He is a Render Tracer, using loopholes that can undo magick to stop rogue sorcerers. But his next hunt will throw him into a world where he can't trust anything, not even his own eyes.

When Keluwen finally escaped her fourthparents' home and set out on her own to become a thief, she never thought she would one day be killing her own kind. She honed her magick on the streets, haunted by her past, hunted by Render Tracers, and feared by a society that hates what she is. Now she joins a crew of outcast magicians on a path of vengeance as they race to stop an insane sorcerer who is trying to make himself a god.

Corrin is a sword fighter first, a drinker second, and a...well, there must be something else he is good at. He'll think of it if you give him enough time. He is a rogue for hire, he is terrible at staying out of trouble, and someone always seems to be chasing him. When he gets caught up in a multi-kingdom manhunt, he finds himself having to care about other people for a change, and he's not happy about it.

They are about to collide on the trail of a man who is impossible to catch, who is on the verge of plunging the world into ruin, and who can turn loyal people into traitors in a single conversation. They must struggle against their own obsessions, their fears, ancient prophecies, and each other.

All they have to do is stop the unstoppable. Simple.
