Relinquished (Paperback) (ISBN-13: 9780645087444)

A bargain struck. A sacrifice made, and the price is high.

Loki's hound son grows stronger and his temper shorter, igniting fear in the gods of Asgard. They must restrain him before he becomes too strong to handle and brings Ragnarok upon them.

Desperate for a tougher restraint, Kara and Thor, accompanied by her trusty dragon and friends, travel to the realm of Svartalfheim, seeking the dwarves' expertise.

They soon learn that they will gain nothing without sacrifice.
