IIn The Casitians Return, life on Earth changes forever when aliens of human origin arrive with a startling new mandate, and the technology to enforce it. The aliens are here--and they are us. Or rather, they are human beings from another star system who have come to reunite the two branches of humanity, whether we like it or not. These aliens (who are called Casitians since their planet is called Casiti,) are mandated by the Galactic Council to make earth a more enduring, peaceful and sustainable community -- not so much for people, but for dolphins, the true galactic citizens. Predictably, many Earth humans resist, and the Casitians unveil a surprising solution: Earth humans are given the option to migrate to a whole new planet. There is Joel, a SETI scientist, who is first denounced, then vindicated, when he discovers an alien signal. Marianne, a whip-smart programmer, is chosen as the first contact, and she has to juggle the complexities of telling the world even as she is emotionally drawn to the mysterious Casitian, Ja'el. Follow them and a whole host of Earth and Casitian characters in this engaging exploration of what might happen when humans meet… ourselves.
