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. Perfect for fans of The Dark Tower, Firefly, Guardians of the Galaxy, Terry Pratchett, Ben Aaronovitch and Jim Butcher.
