Rue Silverclaw has been hunting monsters since she was old enough to hold a sword, but her latest job isn’t one she signed up for. A man calling himself the Archdruid has tasked her with killing the mysterious Moonchild – and he means to hold Rue’s mother hostage until it’s done.
Nor is his request all it seems. The Moonchild is surrounded by an enchantment only Rue can pierce, and by secrets that have lain buried for hundreds of years. In doing the Archdruid’s bidding, Rue risks unleashing a new threat – none other than the dark magic she’s carried all her life.
A magic so powerful that its last wielder almost tore the world apart. Can Rue both save her mother’s life, and stop herself doing the same?
