The Harrowing Path by Cleave Bourbon

The dark forces of shadow are on the hunt… …and Lady Shey knows who they're hunting. An innkeeper’s son and his friends are caught up in the plans of the sorceress, Lady Shey, and her companions who are on a quest to restore magic and stability to the kingdoms. But magic is outlawed in the lands where she is to train the fabled descendants of a time past, forcing her to get creative. Moreover, the enemy has created an almost undetectable shapeshifting monster who is after the progenies of the past for a very different reason. Unable to detect the creature, Lady Shey may be unwittingly leading it directly to its prey.
