Elysia is created in a laboratory, born as a sixteen-year-old girl, an empty vessel with no life experience to draw from. She is a Beta, an experimental model of a teenage clone. She was replicated from another teenage girl, who had to die in order for Elysia to exist. Elysia's purpose is to serve the inhabitants of Demesne, an island paradise for the wealthiest people on earth. Everything about Demesne is bioengineered for perfection. Even the air induces a strange, euphoric high, which only the island's workers-soulless clones like Elysia-are immune to. At first, Elysia's life is idyllic and pampered. But she soon sees that Demesne's human residents, who should want for nothing, yearn. But for what, exactly? She also comes to realize that beneath the island's flawless exterior, there is an under­current of discontent among Demesne's worker clones.
