The Monster of Selkirk Book 1: The Duality of Nature

Monsters come in many forms, and not everyone knows a monster when they see one. After three hundred years of monstrous, feral elves plaguing the island nation of Selkirk, everyone believes they know what a monster is. Humans have learned to live with their savage neighbors, enacting a Clearing every four years to push the elves back from their borders. The system has worked for centuries, until after one such purge, a babe was found in the forest. As Tallis grows, she discovers she isn't like everyone else. There is something a little different that makes people leery in her presence, and she only ever makes a handful of friends. But when the elves gather their forces and emerge from the forests literally hissing Tallis's name like a battle mantra, making friends is the least of her troubles. Tallis and her companions find themselves on an unwilling journey to not only clear her name, but to stop the elves from ravaging her homeland.
