The fourth book in the page-turning SPELLSLINGER fantasy series. Kellen and his murderous squirrel cat, Reichis, are on their own. They've heard rumour of a mythical monastery, known as the Ebony Abbey. It's a place that outsiders can never find - but Kellen is getting desperate. He's been told that the monks inside the Ebony Abbey know more about the Shadowblack than anyone else - and that they even know how to cure it. Then Kellen and Reichis are separated and for the first time, Kellen must face the world alone - and venture deeper into shadow magic than he ever knew he could.
