The Last Dragonlord

Dragonlord Linden Rathan, last-born of a race of immortal weredragons, has spent six hundred years alone, searching for his soultwin while his fellow Dragonlords watch over humanity's Five Kingdoms.

When the Queen of Cassori dies mysteriously, Linden and the other Dragonlords are called upon to prevent civil war as two human claimants vie for the regency.
