A terrifying thriller for young adult fans of The Martian and paranormal space adventure that will be devoured in one heart-pounding sitting.

It's been decades since anyone set foot on the moon. Now three ordinary teenagers, the winners of NASA's unprecedented, worldwide lottery, are about to become the first young people in space--and change their lives forever.

          172 Hours on the Moon by Johan Harstad is undoubtedly the best mystery/thriller novel I have ever read. This 355 page Sci-Fi thriller depicts three teenagers, and their once in a lifetime opportunity of setting foot on the moon.This book starts off in the year 2019, nearly a decade after the last moon mission NASA sent. In the last ten years, alien signals have been emanating from the moon leading NASA to launch another mission. But this time, 3 teenagers have been chosen for the mission of their lifetime. The three teenagers have high hopes for the trip, but little do they know that a mysterious alien form is waiting for them on the moon. It is the opportunity of a lifetime if they make it back alive. Johan Harstad does a very good job of describing the setting of the book. It makes the reader feel as if he or she is the main character.I would recommend this book to anybody that loves books that are mysterious and make the hair on a person's back stand up.
