Mirror Earth Revisited - Mirror Earth, #2

In this sequel to "Mirror Earth", Elisabeth and Roger live happy lives on the other Earth. They are still adjusting, but there are many people around to help them along. Denise, Walter, Jane and Sarah are back on their home Earth. Due to what's called the failure of the time-fluxer project things aren't that great. The scientists go on because they have to. Unfortunately they only have each other to fall back on because Professor Holger has little love left for them.
Everyone thinks the troubles with the time-fluxer are over. It's time to think again.
