Dragon Assassin 4. Downfall (en Inglés) - Arthur Slade

An ancient enemy rises from the seas...

Brax and Carmen are exploring the ocean when they come across the dead body of a dragon on an island. He was an outcast, living far away from Drachia. And he was just recently killed. It turns out that an old enemy that the dragons believed were all destroyed have returned. And they want revenge. One dead dragon at a time...

But the only way to defeat the mightiest of giants is to face him on his home turf. It is a land like nothing Carmen has ever seen. On a royal mission, Carmen travels to the land of giants. A fabled country that no mortal has visited for thousands of years (and lived). It will be a challenge unlike any other. It's a good thing she has Thord on her side. And one more ally she never dreamed she'd see again.
