Bloodfire Quest
The quest for the missing Elfstones has gone badly awry. The Druid Order has been decimated, and its surviving leader and her followers are trapped inside the Forbidding -- the hellish dimension imprisoning the most dangerous creatures banished from the Four Lands. But the magic barrier that surrounds the Forbidding is crumbling, and an evil horde is poised to break free. The only hope lies with a young Druid faced with a staggering choice: cling to the life she cherishes or combat an army of darkness by making the ultimate sacrifice.
The quest for the long-lost Elfstones has drawn the leader of the Druid order and her followers into the hellish dimension known as the Forbidding, where the most dangerous creatures banished from the Four Lands are imprisoned. Book #2
