This Shared Dream

The three Dance kids, seemingly abandoned by both parents when they were younger, are now adults and are all disturbed by memories of a reality that existed in place of their world. The older girl, Jill, even remembers the disappearance of their mother while preventing the assassination of John F. Kennedy. In this novel, the changes in history have created a present world that is in many ways superior to our own, while in other worlds people strive to prevent their own erasure by restoring the ills to ours.
