Throughout history there have always been people willing to sell their soul for the right price. Akane, a shape-shifting fox demon from Japan, knows all about it-for the past two hundred years she's the one who's been buying them. ¿But one thing Akane's always wanted is a soul of her own, to be human and experience firsthand the things that are missing in her, like love and morality.¿When she strikes a deal with a troubled scientist and uses her unique ability to power his controversial device, taking medical science to a place it was never meant to go, she unwittingly becomes trapped inside his experiment. ¿Now, to reclaim her power and recover what was lost, Akane must navigate the dangerous waters between love and loyalty with the scientist and his only friend, a blind priest, two men she barely knows and scarcely trusts, while evading an ancient evil that's determined to kill them all.
