When all you need is beauty, and the Devil's serving boy needs you to play dead—with Hella, the Norse Goddess of Death.

Ruby Rush lost her face to a fire and has been in hiding ever since. When her best friend brings her a magical mirror, she finds herself through the looking glass with Roger Rok, a demigod son of the Norse God of Love.

He's looking for a berserker sword to stop the end of the world, and in return for her help, promises her a beauty beyond her wildest dreams. But bargains, as well as mirrors and hearts, are made to be broken—especially when Ruby comes face to face with Hella and is whisked away to her icy realm of death.

While Ruby fends with Hella, Roger must deal with the conflicting desires of Odin, Loki, Hella, and Freya while a shapeshifting horsefly turned cockatoo leads or misleads them on their journey to stop Ragnarok.

Ruby tries to protect her heart, and Roger does his best to charm and protect her into helping him navigate modern day San Francisco. As the end of the world draws near, will Ruby discover that Roger's professed love is not an illusion? More importantly, will Ruby and Roger find what they're truly looking for?
