Ten days to keep a lie.
Ten plagues if you deny.
Ten ways to watch them die.

Five years ago, when Detective Jena Campbell put the Leviticus Killer behind bars, she locked her darkest secret away with him. Something never meant to surface. Something better left to rot with the madman who had destroyed so many lives.

When a strange man calling himself Azrael appears on social media with threats to unleash ten plagues, ten deaths, in ten days, unless Leviticus is released, Jena is forced to reopen that door and face her past.

Unable to share what she knows, she turns to the only man who can help her find Azrael before he kills again, the man she condemned. Jena quickly learns the only thing more terrifying than facing him, is facing herself.
