Iduna's Apples

In Book 2 of the Valhalla series, Thor and his kin are depleted by the battle for the White Oak Yggdrasil and are in desperate need of Iduna's apples--the sacred fruit that grants immortal strength and long life to the Norse gods.

But Iduna's Grove in modern-day Norway comes into harvest only once every four hundred years--just in time for retreating glaciers to free the dreaded Frost Giants from their icy prison. The gigantic and eerily courteous Frost Giants hold the harvest ransom and demand wives: Freya, Saga, Heimdall's girlfriend Maggie, and even teenaged Norse Witch Sally Dahl.

Will Heimdall and Thor track down the Frost Giants and the apples before succumbing to sudden mortality? Can Sally atone for accidentally calling up an army of old lady Berserkers to stand against Odin? Is that Thor in a wedding dress? And is there a darker, more sinister enemy on the loose, targeting both the Norse gods and their Frost Giant foes?
