The book is a selective compilation of messages transmitted through Dr. Milanovich, via a microcomputer from beings who identify themselves as Celestials from the star Arcturus and members of the Galactic Command. These transmissions describe, in detail, their home, starship, mode of functioning, way of life, their mission, and Earth's transition into the New Age. One of the more unique features of this book is that the Arcturians state they are preparing the way for the return of the Most Radiant One, who they call Sananda, Jesus the Christ.
