Awesome adventure

Love these stories! Give me crazy travel fever! Love all of the information I learned about places I have been to and never knew previously . The series was difficult to determine whether or not it came after The previous double Cross series. Presumably it's the last four books out of all 39 clues. What a ride! Have turned many others on to what a great adventure this is! Well written and incredible narration!

Totally twisted

It was good because all the main characters were spared. The end was totally unlike all the other books. We liked it because it was about space.

PG Rating**I was very disappointed to see they made a teenage character "come out of the closet"This is inappropriate for kids😝

I was very disappointed because they turned one of the teenage characters into a gay character. I find this extremely inappropriate in a children's series. I will not recommend this series to any other families. Very disappointed that they had to introduce this story line into an otherwise great series.

Great As Always, but drop the political preaching!

This whole series has been awesome, but the last 2 authors, have decided to throw in environmental sermons at random moments. It is an eye rolling annoyance that takes you out of the story and instantly became this "arrogant author" moment. Please just tell the story and stick the political preaching up your.......
