55年后。快乐是一种EN·VOI。琼南多信托的特工。信托是企业拥有的城市，是现代社会的核心。她为信托公司纠正错误。她是优秀的。完美。对自己太苛刻了。驱动的。在某些地方几乎是传奇。直到有一天，一个声音在她脑海里响起试图让她背叛她所相信的一切。
Fifty-five years from now. Joy is an EN·VOI. A special agent of the JONANDO TRUST. Trusts are corporate-owned cities that are the centerpiece of modern society. She rights wrongs for the trust. She is excellent. Perfection. Hard on herself. Driven. Almost legendary in some parts. Until one day a voice pops in her head trying to get her to betray everything she has ever believed.
