Lucifer's time has come for the outcome of his failed rebellion to be righted. When the Lord of all Demons is seated on Heaven's throne, he will revel in the sight of God powerless at his feet. All he requires is the one thing he could never claim to possess, until now—Mercy.

Mercy Aymes always thought she was a normal girl living a normal life, until five years on from the mysterious disappearance of her parents that left her world a seething pit of black, she finds herself thrust into the chaos of unfamiliar territory. It’s more than the torments of her past that stalk her through the cold and lonely halls of the Lincoln boarding school.

In a desperate bid for survival, Mercy races for an escape from the wickedness of the school’s notorious bully, and stumbles on the secrets of the Lincoln towers, hidden from the mortal realm for hundreds of years. With the blinders torn from her eyes, Mercy’s world fractures at the sight of true monsters—but the eyes of their King are only for her.

Though captivated by the discovery of an odd array of Gargoyles, Mercy finds more than solace in the silent presence of one she favours above all. But when a powerful connection to the stone figure claims her heart, it’s not long before the mysteries of Mercy’s life unravel.

The discovery of unfavourable blood ties propels Mercy into an age-old war that splits the realms and tears her heart in two. Soon, she must choose which side is to dominate her future, as she faces unfathomable dangers from both forces.

The Archangels want her dead and the Devil wants her to lead. But whose side are the Gargoyles on?
