Countdown (The 39 Clues: Unstoppable, Book 3) Hardcover – April 29, 2014

This book is really one of the best of the entire series. I might have thought Dan, Jake, and Atticus might treat Amy like she was fragile, but no. They're heaping the silent treatment on her, and I understand why.I have to say, I loved Cara Pierce in this book, just like all the other ones. She is strong, smart, and resourceful. Her brother, not so much. She finds ways to overcome all the odds.I cannot wait to read the last book. Whoever the next author is, good luck matching this book's level! It was amazing. This series just keeps getting better.

This book continues the saga of Amy and Dan and leaves you wanting more. It is very well written and follows the story line well even though the series is written by different authors. I have told many of my students about it and have made it required summer reading for them. Once you get into the series you do not want to put it down.

All the 39 clues books are great! My 10 year old loves them. He started with the original and is now on the third series. They keep his interest.

Great series for preteens and even young teens. Exciting and informative as they travel all over the world and go into different historical places. The boys I get the books for have been reading this series since the very first 39 clues books. This is the 3rd in the continuing series. The 39 clues, then the vespers and now unstoppable which we just finished. They are coming out with the next series that continues next year and the boys can't wait.

Super fun to read 😊 😊 😊 😊. 😊 😊 😊 😊 😊 😊 😊 😊 😊. 😊 😊 😊😊 😊 😊 😊 😊 😊

Excellent!I know these books were written for teens & I only started reading the first one because my daughter downloaded them to my kindle to read....BUT I am hooked!They are well written, suspenseful, exciting & I keep downloading the next one!Thank you for hours of enjoyable entertainment!

My 11 year old son loves this series.

This is one of the best 39 Clues I've ever read!!!! The thrill and drama is enough to keep you wanting to read more!! I cant wait until I get the fourth book!! I hope this series NEVER ends!!😁😊

Great but waay to much action. It was literally one thing after another again and again. Apart from that it was good

I love this book so so so so much it is hard to believe! I finished it in a day

fantastic book, highly recommend it!

This #3 book in Unstoppable series is better than the previous two books, but the storyline is still too predictable.I'll not continue with this series.

I've burnt it, too short for the expectations I had for it. Moreover, too many bad things happening... I can't wait to read some great news. I already miss Pony. Is there any way he could come back?
