This is a great book! I went to bed with an advanced copy prepared to just look it over. Fast forward til morning when I finished. I got up and told my husband - I just read a book that we're going to see as a movie, mark my words! I can't wait to see how they get the cat to float in space. I loved the love story, too. I actually teared up when Jack Medaris found what he found on the moon - can't say too much or I'll give the plot away. Anyway, want to enjoy a thriller which is also a love story which also tells you a whole lot about getting into space and staying there? You can't go wrong with this book.
