In a warlike land of wind and sunlight, "ringed by a restless sea," live Rhaskos and Melisto, spiritual twins with little in common beyond the violent and mysterious forces that dictate their lives. A Thracian slave in a Greek household, Rhaskos is as common as clay, a stable boy worth less than a donkey, much less a horse. Wrenched from his mother at a tender age, he nurtures in secret, aided by Socrates, his passions for art and philosophy. Melisto is a spoiled aristocrat, a girl as precious as amber but willful and wild. She'll marry and be tamed--the curse of all highborn girls--but risk her life for a season first to serve Artemis, goddess of the hunt. Bound by destiny, Melisto and Rhaskos--Amber and Clay--never meet in the flesh. By the time they do, one of them is a ghost. But the thin line between life and death is just one boundary their unlikely friendship crosses.
