Pride has commanded an impossible feat: Octavia must finish The Devil’s Trials and eliminate the devil, or find herself forfeit to him.
Meanwhile, Niklaus Heira has stolen her away to the Wastelands Rebellion. Too far from the trials, she finds herself stranded in a hive of anger and treason. Where they demand that she join their attack on Eternis, unaware of the devil whispering in her ear, watching their every move.
Escaping the rebellion alongside an unlikely ally, Octavia must find her way to Desidia, the home of Sloth, to face her next trial. In a land where humanity is forced into an endless slumber, she falls prey to chaotic worlds of dreams and nightmares, exploring realms that offer everything she desires most, from forbidden love, to those lost from her past, with only one catch, if she stays too long, she may never leave.
Confronted with a loss that leaves her reeling, Octavia is tempted to hide from reality and exist only in the world of her dreams. Except Pride, Sloth, and Samael may all lay claim to her soul, and she can’t escape the devil in her dreams.
