A Shadow on the Glass by Ian Irvine

With this stunning and original debut, Ian Irvine begins the saga of The View from the Mirror, a brilliant epic fantasy that rivals the works of Robert Jordan and J. V. Jones. "Once there were three worlds, each with its own human race. Then, fleeing from out of the void came a fourth race, the Charon. Desperate, on the edge of extinction, they changed the balance between the worlds forever..." The Tale of the Forbidding In ancient times the Way Between the Worlds was shattered, leaving bands of Aachim, Faellem, and Charon trapped with the old humans of Santhenar. Now Llian, a Chronicler of the Great Tales, uncovers a 3,000-year-old secret too deadly to be revealed-while Karan, a young sensitive, is compelled by honor to undertake a perilous mission. Neither can imagine they will soon meet as hunted fugitives, snared in the machinations of immortals, the vengeance of warlords, and the magics of powerful mancers. For the swelling deluge of a millennial war is rising, terrible as a tsunami, ready to cast torrents of sorcery and devastation across the land...
