Conclusion to Watt-Evans’s fantasy trilogy (Dragon Weather, 1999; The Dragon Society, 2001).
Previously, young Arlian, sole survivor of a dragon attack on the village Obsidian, accidentally ingested a mixture of human blood and deadly, corrosive dragon venom—and thereby became a “dragonheart.” Charismatic, strong, fast, and invulnerable to most poisons, Arlian is destined to live a thousand years. As a downside, he will become less and less human and eventually will die when a new dragon claws its way out of his chest. Unlike most dragonhearts, Arlian burns for vengeance upon the creatures that made him what he is. And now he knows two crucial facts: dragons, once considered invulnerable, can be slain with weapons tipped with obsidian; and, though dragons don't eat, they prey on humans because they consume souls! Arlian, taking advantage of the dragons’ midwinter torpor, slaughters them as they slumber in their caverns. But as the number of dragons dwindles, so does their magic, allowing the wild magic, evil wizards, and monsters of the Borderlands to encroach on the Lands of Man. After journeying into the Borderlands to consult with the powers there, Arlian wonders why the mixture of human blood and dragon venom is such a potent elixir. Cold-bloodedly, he experiments on animals to see whether the elixir might create other kinds of magical beings. The results are disturbing. And, naturally, his plans will be violently opposed by the other dragonhearts and their surviving dragon allies.
Should satisfy existing fans but won't tempt many newcomers.
