In the heart of the Great Forest, nothing is as it should be. Sir Vladisal and her Knights of Boska are lost and far from home. The son of their Duchess has been kidnapped, spirited away to a nameless place within these dark and endless woodlands. Vladisal is his only hope, but an evil has come to the Great Forest, an evil that is corrupting the trees with demons born from ancient magic.

If Vladisal is to save her Duchess' son, if he and the women of Boska are to live through the horrors of the Great Forest, then she must place her trust in Abildan the assassin. But Abildan hails from an age-old enemy, and she once served the very evil they all must fight to survive.

In The Bone Shaker, the author of The Relic Guild delivers his most potent tale yet; a powerful story of valour, betrayal, dark magic, blood and death, but also of hope. Epic fantasy distilled into a novella, in which traditional gender rolls are turned on their heads.
