The Community is your first responsibility as a Citizen. So says the First Edict of post-Reformation Sindra. Maribel is a new mother of twins in this bioengineered, telepathically networked society of comfort and safety, where the only relationship that matters is the one between a Citizen and her Community. But Maribel is also a scientist, and scientists follow facts-wherever they lead. Her search for the truth awakens emotions in her she never knew existed, uncovers ancient powers long hidden in Sindra's history, and has the potential to destroy her Community. A dying planet . . . A desperate parent . . . A daring plan . . . IRRADIANCE is the story of Maribel's choice.
