A Whisper in the Shadows - Rangers of Laerean, #1

When the Ranger Baric meets the exotic and alluring woman from Vaar'da, called Whisper, he agrees to assist her on what seems a simple rescue mission that soon turns into something far more complicated than he expected. Their journey soon becomes a deadly and suicidal quest into the Great Divide, an area of Hir where men fear to travel, into the realm of the demonic Manenase, who live under a great volcano in the center of the Boiling Sea.
The fate of Hir depends on the courage and skills of the heroic Rangers and their small Vaar'da companion, as they struggle to save the world of Hir from impending disaster.
