This book was different because if you haven't read the past books (like me) you can learn who the characters are and learn what is happening soon. The book is set up like this: It starts with Conner (the main character) is on yacht in the middle of the sea and they are getting attacked by pirates. I don't want to spoil it to anyone who has read it. (Still even though there is the first chapter up above and it shows a lot more then I said) But the whole book is a story of trust, betrayal, adventure, getting attacked by pirates and (of course) a ransom for 100 something (not going to say it. If you have the book, then you should know the amount unless if you have not read to the point yet.) I think I would rate it 4-5 stars.
I liked the book, but I'm annoyed that it ends on a cliffhanger. I like the theme of the plot (the future, in a 'Jungle' with deadly creatures, well all of the usual plane-crash-with-robot-enginers-and-some-other-kids-including-a-kid-with-a-old-katana-and-they-end-up-in-a-jungle-with-crazy-creatures) I would rate it 5 stars.
