Renata wakes with no memory of her life's details. Names and faces linger at the edges of her mind, but everything else is a blur. Still, her fingers remember melodies on her instrument-along with skills that feel disturbingly natural, like lockpicking.

When the Gilded Triangle, a powerful society devoted to Nainaur, God of the Heavens, discovers she holds a contract with a High Devil, they make her an offer: descend into the Hells and retrieve an ancient relic of their god. In return, they promise answers.

Now caught between Heaven and Hell, past and present, Renata-now simply Ren-must confront the question at the heart of her journey: is her past worth remembering... or better left buried?
