In a world where magic reigns and beast demons serve as power-boosting familiars, Eden Wynne, an outcast low-class mage has never managed to summon one.
Despite his family's wealth and reputation, Eden is branded a failure. After countless breakdowns and barely surviving the pressure of expectation, he makes one final promise: summon a familiar, or end it all.
Then he succeeds.
But what he summons isn’t a typical familiar. It’s Sylas a six-foot-eight, sassy, furious demon prince who has no intention of obeying a pathetic, suicidal mage.
Eden wants control. Sylas wants blood.
It’s hate. It’s angst. It’s a soulbond neither of them wanted and now neither of them can escape.
Who will break first?
