Book 2.5 in the Crymzon Chronicles 
Sins. Betrayal. Redemption.
Every century, the God of the Underworld lets seven souls participate in Nekrojudex to become a new Head of Sin.
While everyone is eager to enter the trials to make a name for themselves, Avira is plagued by something more substantial. Since joining the Underworld, she lost her memories like everyone who touched Otyx's hand when departing their former life. Her afterlife becomes more complicated when she meets the Prince of the Underworld and becomes one of the participants.
What will she do when the God offers her the choice between regaining her memories or aiding the suffering souls surrounding her by claiming a House of Sin?
(Otyx is book 2.5 of the series and is best placed between Hunteress and Conqueress for the best reading experience)
