For centuries,the kingdom of Joseon has hunted down sorcerers and shift shapers branding them as demon and erasing them from history.Moon Sihyun,the last known surviving demon sorcerer,has spent his life in hiding,concealing the dark tattoos that mark him as a threat.But when he and his twin brother are captured,he's thrown into the heart of the palace,straight into the hands of Jin Muwon,the crown prince cursed to die before his 30th birthday.

The only cure?The young blood of a demon sorcerer.Bound by an ancient ritual,Sihyun is force into a dangerous ritual,one that demands he stay close to the very man whose family slaughtered his kind.Muwon drains Sihyun's magic,inching closer to survival.But the longer they're together,the more their fates tangle in ways neither of them expect.

Yet Sihyun has a plan.He doesn't intend to simply be used and discarded.He plans to burn the kingdom to the ground.
Will he break the curse or destroy the man bound to it?
