The Valghians capture Riliha so they can strongarm the Atlandians into surrendering. The Atlandian soldiers engage in the battle to rescue Riliha and Kaina, but aren't successful. Riliha manages to free Kaina while she remains in captivity.
A world blanketed in an endless and ever-growing ocean of snow. The people eke out a living, either huddled around the roots of enormous trees dotting the surface, or high in the canopy, which spreads over the planet's atmosphere.
A chance meeting between Kaina, a youth from the canopy, and Liliha, a young woman from the surface, sets off a chain of events that will change the fate of the world.
