Soliloquy of Seasons (Lacuna Chronicles #4)

The cycle of seasons on Ceres, a temperate and bountiful spring and summer season followed by a horrifying and extended freeze, rules the minds and lives of all inhabitants of Earth’s third sister planet completely. Cereans are an industrious people bound strictly by tradition and by their original colonization directive-- be fruitful and provide the much-needed sustenance for the sister planets.
In Whitewater Valley, Attis is something of an outcast. Born a spring child with the mark of fire, a telling sign of misfortune, Attis knows firsthand the horrors of the freeze and the deadly consequences of the sleeping sickness. However, it is not the dangers of the freeze that haunt Attis, but the lingering childhood memories of a mysterious onyx-eyed boy in the marketplace.
When memories once again become reality, and Attis finds himself behaving in ways that break every Cerean tradition, he must discover for himself his place on Ceres and in the universe.
