“When the sun died, the world didn’t end. It changed.”
Kael Serrin is one of the last survivors of a world swallowed by twilight. When humanity fled into bunkers and shadows, something else came through: The Rift—a cosmic wound that spills horrors into the world and leaves only monsters in its wake.
Those who survive the Rift’s touch are changed. Marked. Cursed.
Kael wakes to find the Mark of Dusk burned into his flesh and a new power whispering in his mind. Now taken to a brutal facility known as the Riftline, he’s forced into a lethal training program with others like him—test subjects turned weapons in the war against the Hollowborn.
But power comes at a price.
The Mark feeds on memory, emotion, even time—and the more Kael uses it, the more something inside him begins to awaken.
He doesn’t know who to trust.
He doesn’t know if he’ll survive.
He only knows one thing:
He has to get back to his sister—even if it means becoming the very monster the world fears.
