There are 3 books in this series by Gordan Korman. These books are short compared to some other books also written by Gordan Korman, like Masterminds or Ungifted. I read each book in about an hour. Because of that, what you can do is obtain all 3 books, and whenever you have free time, you can read all 3 books.
This series is about 4 kids, attempting to be the youngest people on the planet to get on top of Mount Everest. They face several problems along the way, and in the end, it is doubtful if they are able to get to the highest point on Earth. These books were super enjoyable to read, and my favorite would be the last book, the Summit.
What I would have liked would be that Gordan Korman made one whole book, with 3 sections in that book. Aside from that, I think this series is just perfect. There is the right amount of suspense, excitement, and more. I really enjoyed reading this series, and I think you will too.
I can easily rate this series 5 Stars, with no hesitation, and I can recommend it for ages 10+. I think some kids who are younger than 10 can read it, because of the short length, but the book itself might not be appropriate, because there is some apathy, death and more.
