Low Road: Elf Realm Trilogy Book1 by Daniel Kirk
When Matt and his family move to their family's new development, they don't realize that they've inadvertently stumbled into the middle of massive upheaval in the Fairy world. With the elves' territory disintegrating, and dark factions looking to seize control, apprentice mage Tuava-Li must defend her territory - even when that means cooperating with Matt, a human and their natural enemy. Matt just may hold the key to keeping the elf realms from certain destruction.
