Stop the World, I Want to Get Off

Looking at the bewitching night sky observing all the beautiful stars it's easy to imagine about all the other worlds that are out there. It's possible to have other planets exactly like ours in a parallel universe. Daily decisions are made from small seemingly insignificant ones to life changing ones. How often are life choices reflected and people wonder what if? The first book of a trilogy.
Georgie was a daydreamer often wondering whether she'd made the right choices in life. Her marriage to Steve had hit a low point and they are living apart. Their son Jake is always trying to bring them back together.
Georgie had often wondered whether she ought to have taken up the chance to live in America rather than marry Steve. By chance she sees a double of herself on American television which coincides a business trip she is to attend there. When there she challenges her double. She discovers that Gia her lookalike is from a parallel universe and picked up her life.
The women try to work out a way to get back to their respective lives. Gia's planet is the same as earth but changed purely by someone taking a different thought and action.
Their adventure is fraught as they swap lives, Georgie stays in America to live the life she regretted giving up, soon realising it wasn't meant to be. Gia goes to England and faces temptations of Steve who is the equivalent of her husband Sen, who she desperately misses. Both women have their ups and downs and are challenged constantly with being caught out and trying to work out who they can trust.
