An exciting science fiction novel that pushes the limits of scientific imagination. Mr. Reynolds has a Phd in Astronomy and worked for The European Space Agency for 13 years. Now, he is a full time science fiction writer. This novel explores behavior of humans when presented with arduous undertakings and reveals our darkest fears and how we try to cope with them in our unique way. In a science fiction frame, Reynolds tries to state that what is wired in us is not pure evil or pure goodness but a mix of them both. How much of each component you have in you will determine your course of actions and makes who you are. Because I'm a total geek, I loved it. Give it try and you might love it too. @shakirbahzad
