They say revenge is a dish best served cold. For Kyla Marshall's sisters, it's best served straight from the fiery depths of Hell.

Three months ago, Kyla made a decision - a simple act of survival - trading her sisters' souls to save her own. Little did she know that one decision would trigger a deadly game of supernatural chess.

Whilst struggling to control her newfound powers and the darkness they unleashed, Kyla finds herself torn between two supernatural forces—her handsome alpha werewolf whose love anchors her, and her swoon-worthy demon demi-soul whose very existence ignites her.

When DCI Spencer Phillips begins investigating a string of violent and mysterious murders, Kyla suddenly finds herself thrust into his world. As dark truths surface, Kyla discovers that destiny has a way of revealing itself in the most unexpected ways.

But Spencer is the least of Kyla's problems.

Her sisters have returned with nothing but vengeance in their hearts and all of Hell's power at their fingertips.

And they won't stop until they've made her pay for her sins.

In a realm where magick and vengeance collide, death is only the beginning. Step back into a world of supernatural seduction and deadly revenge - where even Hell can't calculate the cost of survival.
