The Magic Queen by Jovee Winters

Baba Yaga is probably the darkest of all the queens. An unrepentant bad girl, she has no time for men, or something as pedestrian as love. Too bad Calypso and Aphrodite never got that memo. They've decided to make the witch their pet project. Baba's choice is simple, fall in love with the male they found her, or die.

She'd laugh, except for the little fact that they're totally serious. But Baba has never been a quitter, she'll go to that male, she'll even willingly go through the goddesses ridiculous "games," what she won't do is fall in love.

At least, those were her plans until she stared into the ice blue eyes of a Viking god and realized her life would never be the same again...
