Seven Deadly Demons

As a child, Selene was left at the foot of the White Tower—given to the sorceresses who train those with magic. Her life has been spent honing her powers. But she can't fully join their ranks until she fulfills a single, impossible task: bring the Demon King, Lust, to his knees. Lust has ruled his kingdom for centuries. He is the reason his people live without remorse and indulge in their senses. Life is mundane and boring… until he runs into a dark-haired enchantress with eyes the color of the night sky. With one whispered sentence, she changes everything. I'm the beginning of something new.

Varya lives in the shadows. As a tomb raider, it's easier that way. Known for obtaining the unobtainable, she risks life and limb to provide for her small desert town: a magical chalice with never-ending water, an amulet that heals, a map that shows where all the other magical objects are. However, the last stolen treasure came with a problem—the Demon King, Greed. When she finds herself saddled with an injured demon, tracked by a horde of warriors, and effectively lost in the desert, well, what's a girl to do?

Katherine lives in the shadows of her village. Injured as a child, she isn't a suitable match for marriage. So, instead, she dedicates herself to having some purpose in the town. Stitching people up after Gluttony has his way with them makes her realize she could be more of a solution than a problem. So she makes the trek up to his castle and offers him a deal he cannot refuse. Her blood, unlimited, if he will leave the rest of her town alone.
