Tal is a Chosen; a manipulator of light through the precious Sunstones-- all that gives light in his world, eternally dark beneath The Veil. He lives in the seven-turreted Castle; the only human dwelling in all the dark world, with a level and a tower for each color. Once a year, his family Ascends into the spirit realm of Aenir, where light and color still reign, and where one day he will bind a spirit being to himself to become his Shadowguard, taking the place of his natural shadow and becoming his life-long servant and companion. However, lately trouble has beset Tal's family; his father has disappeared (and with it the family Sunstone, their only way to Ascend to Aenir), is perhaps even dead, his mother sickens and hovers on the brink of death, his younger brother has been kidnapped, and enemies he does not understand are suddenly dogging his every move. In a desperate attempt to procure a new Sunstone to save his mother, Tal falls from the Red Tower, into a world he finds is not so dark and empty as he always believed. So much of what he thought he knew is now being challenged, especially by the fearsome would-be warrior girl Icecarl, Milla. The unlikely pair find themselves bound to one another and to a Quest-- to return to the Castle (no small feat across the dark world of Ice) and obtain two Sunstones; one for Tal, and one for Milla's Clan.
