Flashfall

This started really well but (1) got worse and worse in terms of plot and world building and (2) made no sense whatsoever.

I have never read such bad world building and a book which throws in so many things that don't go together, don't fit, don't make sense. I really liked how it started but it felt like the author didn't want to write anymore at the halfway point and just gave up.

What a waste of reading time...
