(This is a extremly long review it might take about 3 mins to read.) This is more a review for all 3 books. Let me tell you that i am 14 and this is an amazing book. I have had this book sense the 2nd grade and it is amazing. I have all 3 and it is still one of my favorite book seires. I have read Moby Dick all of Harry Potter and much more but this story is amazing. The story and lore gets better every book and in my opinion is an amazing series for any age. (Spoilers ahead) The fact that for the whole first book we were lead to believe Kepler had a teleportation power along with the cave of secrets and abigal leading up to be the villian was an amazing start only to figure out that Kepler has time travel in the second book. Bens relization in the book of the lines between hero and villian are amazing too. The finial book is awsome. The begining is near perfect with the time travel and then the mini arc when ben meets Magnific to pass time is nice to with Ben understanding he can be a hero even without Nix and understanding how important magnific is to the people of his town. I do think this part should jot have been 40 pages but its still nice. I do wish Jordan was more evolved in the final book. Its a shame to see him not as involved. I wish we got to see more with everybodys friendship aswell with Ben noah penny and jordan. My only complaint about the whole series is i wish it was longer lol! Overall this series is awsome. Even as a kid it was easy to follow and understand. I know its made fir younger kids but it still a great series for a teenager in my opinion. 10/5 stars!!!
