The story started well with three separate narratives separated by 1000 years but linked by a central character, Leah, and her search for the afterworld. The separate stories started off compelling, and the futuristic "world" was interesting and thoughtful in it's depiction of a world post a climate change driven apocalypse. The choice of Belize and Mayan culture as a basis for the stories was inspired,I thought,given the Mayan's long term view of the world.

I was so disappointed when the stories went off the rails towards the end. Characters developed too fast and became inconsistent, plot changes seemed random and disconnected and the conclusion was a damp squib. 

Oh, and Gröningen in Germany doesn't have University. Groningen in The Netherlands does. A simple research error.
