A Demon’s Heart by Catherine Banks

Reviled. Rejected. Underestimated.

Zola refuses to be kept in her place where demon society says she belongs; instead, with the help of her legion of werewolves, fae, humans, and other supernaturals, she prepares to do the unthinkable and challenge… everything.
Can Hell withstand her army?
Zola knows that love and loyalty create unbreakable bonds but the Lords of Hell have centuries of experience in war, domination, torture, and wreaking fiery vengeance against rebellions— whatever it takes to stay in power.
The seven Lords of Hell know in order to survive, they must defeat the little upstart demoness… Before it’s too late.
With a legion of devoted followers, Zola will face every attack, every betrayal, and continue her mission to defeat the ones who sought to enslave her.
But will she win her freedom, once and for all, or will she burn in the fiery pits of Hell like others before her?
