Amulet of the Fallen God. Heroes of Harth, #1

When an ancient artifact falls into the hands of a young, inexperienced sorceress, Allsa, a battle-priestess of Thon, finds herself shepherding the young girl through a dangerous land. Their mission: to find an ancient wizard from a tale she doesn't even believe is true. Luckily, she has the help of a grumpy old dwarf, an obnoxious mercenary, an erudite elven wizard, and a new-wave minstrel. Allsa can only wonder at the circumstances that made her the leader of this rag-tag band of adventurers.
But the old Human King is dead and the Elven King is mad, and it's up to her and her stalwart group to save the northlands from the impending Zarrum invasion. Amulet of the Fallen God is an epic fantasy novel in the tradition of Lord of the Rings and Game of Thrones.
