The Wizards of Once #3: The Wizards of Once: Knock Three Times

Third time lucky? Xar and Wish need all the luck they can get! Most of us never fight a war against evil magic. Xar and Wish have done it not once but twice – and now they face a third quest. They’re being hunted by Wizards, and by Warriors, and by Witches. And yet again, they face an absurdly impossible task. Up above, in the treetops, cruel Witches sharpen their talons in readiness. Worst of all, Xar and Wish must confront the frightful Nuckalavee. This hideous critter makes everything else they’ve faced look like a picnic. But with the power of Magic and Iron together, they will prevail. Won’t they?
