Melting the Ice Witch. Dragon's Hoard, #4

The Tribe of the White Dragon has lived in the frozen wastes of the north for thousands of years, but they are slowly dying without their dragon to protect them from the inhospitable cold. In desperation, they kidnap Kam, hoping to use him to breed witch power back into the Tribe. But Kam is not a witch, and there is nothing he can do to save them-until he sees the white dragon encased in ice and all alone and a chain reaction is set off that may save them after all.
