Warstalker's Track (The Windmaster's Bane Series)

Magical tracks of silver and gold connect our world to others. But now an evil wind blows among them all—bringing with it the scent of war... Lugh Samildinach, High King of Tir-Nan-Og, has been deposed and imprisoned, and the throne of Faerie is under siege. Those who would seize its power bear little love for humankind, and will risk everything to defend their weakening borders from the unwitting invasion of mortal land developers—even if it means drowning the entire state of Georgia. David Sullivan, human liason between mortal and Faerie, must summon his friends to aid both races. Armed with weapons of iron and magic, they must rescue the captured Faerie King and forestall the despoilers of David's beloved homeland. But even as the fate of thousands hangs in the balance, a very personal tragedy raises the stakes for David alone...who has discovered just what he stands to lose if he should fail.
