The Iron Sceptre — John White

Anthropos is in danger. So Wesley, Kurt and Lisa are once again magically transported from their home in Winnipeg to help save this threatened land. The Iron Sceptre, the source of King Kardia's power to rule, is in peril. The children, joined by their cousin Mary, are called on to stop Mirmah and her chief sorcerer, Archimago. But to do so, they must travel beneath the Northern Mountains, around Goldcoffin's Palace and into the very heart of Mirmah's kingdom. What awaits is much more than a mere adventure.
