WOW!! This book... 
 It really did creep me out! And that hadn't happened in a long time with a book. Plus it made me really interested about space missions. After reading it I feel like looking into the first moon mission and doing a small research! 
 It is divided into two parts basically, the earth part and the moon part. For me, the earth part was pretty slow and got a little boring at times. But that moon part really made up for the first part!! I am positively surprised! Plus, even though I had concerns about the ending and if the author would be able to pull it off, I have to say, he did not disappoint me..! Overall, a very good job, a thrilling and very creepy novel. Solid 4 stars, I really liked it!
