"If I kill one murderer, the number of murderers stays the same. If I kill more than one, it lowers."

Life should be better on the city island of New Arcadia, but the underworld is very much alive and ruled by self-interest and sin.

Roselin, an eager art student, feels lost and alone when she meets the hardened crime boss Ryu, who uses his Mageía powers to benefit his needs. With every kill he makes, he gains more control over the shadows of the city, literally and figuratively.

Although their morals clash, Roselin can't help falling for him — captivated by his shadows, while Ryu is mesmerised by Roselin and her art. But with secrets surrounding them and an enemy out for revenge, they need to find common ground to survive together.

Sin Eater is part of Arcadia Sinners, a dark and steamy romance series with fantasy sprinkled in.
