Esme “Ez” Nussbaum is an important member of Ofnow, the governmental organization tasked with implementing OPERATION ISHMAEL and monitoring and making the public docile. Ez contends that to deny human nature and to deny knowledge will prove less, as opposed to more, harmonious. For this, the government tries to kill her but fails. Still, she bravely continues to work for Ofnow. Years later, she is able to get the government to at least atone for the past by seeking to return the Jewish race. She meets and befriends Ailinn at a book club. Upon discerning that Ailinn is Jewish, Ez makes her the primary candidate to birth a new Jewish race.
