Aieclo (Ranger Trilogy #3): A Tale of the Dwemhar (Stormborn Saga Book 6)

They seek assassins but they'll find something worse.

Fadis and the crew of the Aela Sunrise travel to the island of Aieclo seeking the Verit Gamblers, a nefarious guild of shadow elves. These mysterious warriors have helped the crew in the past but only a few nights ago they killed an elven king. Their only allegiance is to gold but paying for these assassins is the easy part of this quest.

Aielco is a ruined island, once the haven of the infamous Scourge Siren, the island has become an unstable volcanic wasteland with many strange inhabitants and secrets. When a beloved companion goes missing, it's up to Fadis and Kirla to find their wayward friend.

But a few arrows and some crafty parries might not be enough. An ancient evil grips the land and what before was thought destroyed has been festering and waiting... it will take more than a ranger to stop the rebirth of a demon.

But tell that to Fadis...
