5.0

An excellent informative book that made me learn a lot and fascinated me.
The author is an excellent storyteller and populizer of science. This is not an easy read but I found it very informative and found the theories about alien life very interesting.
There's plenty of books about alien life but it's the first I read that is based on sound scientific theories.
It's not a book you read in one afternoon but it's surely a book that will keep you turning pages.
Highly recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
