Each procedure cycles her through the three different times and in each she makes decisions that have an affect on that particular life, and as the story unwinds we realise that the alternate Gretas are also making their own decisions that will affect her life. Basically they inhabit each other bodies rather than physically jump to each time period.
Interesting was how Felix's stories provide an exploration of the limited choices available to gay people throughout history. Of course the modern Greta knows her brother is gay and encourages him to make choices which are true to himself. What was a bit weak was that the Gretas did not seem to think overly much on how their actions would impact on each other. There could also have been more details to flesh out the time periods but the overall premise of the story is satisfying, and this book will keep you reading to the end, after all you must find out which life will each Greta choose to stay in?
