Mist, Shadow, and Deep - The Crystalline Dragons Saga, #2

A shadow rises to meet the light and, with it, an evil sorcerer. Dusk must choose between what is right and what is easy. In his hour of need, a new face emerges. But is he friend or foe? Only time will tell. Barely escaping with their lives, Dusk and his companions head south, following the mountains as they search for another way through. That is until they're lost within a misty bog that threatens to consume them.
Out of the mist appears a figure who saves Dusk before the monster of the bog can consume him. Grateful and indebted, they head south together toward the port town of Emerald Deep. There's a pass through the mountains there that will lead the party to their freedom at last. But Emerald Deep is filled with mysteries, thieves, and temptation. The moment they arrive, the group begins to crumble, and Dusk is left wondering if his companions ever cared about him at all.
And that's the moment the shadow attacks.
