Now Dan and Amy are facing their greatest threat yet, an enemy who has found a way to use the source of th

The reason I didn't give it five stars is because I'm worn out on behalf of the poor characters. I wish they had let this series go. It was bad enough when they were just being run ragged and in danger all the time. Now they have to be falsely maligned and publicly humiliated, too? The books are still exciting and clever, but I just want all the problems to be solved and over with.

Yay. Another terrible book in the 39 Clues series. I honestly don't understand why Scholastic couldn't have made Into the Gauntlet the last book (of course, with some Amian added in to make it canon). But no, they find random unknown authors to write some angsty nonsensical action romance drama, further deteriorating the 39 Clues canon. And worse, THERE'S NO HOPE FOR AMIAN!

The Good:

...I'm drawing a blank here. Time to go look through the book again...

1) The hacker subplot.

Have I mentioned that I HATE AMY?! Probably yes!
The book generally was interesting, but it was so much tedious and dragging thanks to Amy. There wasn't any real adventure except when Amy locked in the vault. The best part for me was Pony and April May POVs as they gave something different than usual stuff.

Okay, look. I absolutely love the The 39 Clues series. I've read all of them. But Jeff Hirsch fell short in this book. Really, my rating for Breakaway is a 4.5.

Jeff Hirsch did sorta rekindle the flame between Amy and Jake.
Jeff Hirsch wrote an excellent middle.
Jeff Hirsch answered a lot of questions of mine, believe it or not.
Jeff Hirsch emphasized on Amy's doubt and grief on Evan Tolliver.

Jeff Hirsch wrote a horrible, atrocious ending.

The Atlantis part of the book was kind of (just kind of) cool. Honestly, anything to do with Atlantis would gets me interested. However, leave it to Scholastic to write one series too much and ruin the whole goddamn idea. Seriously, most parts of this book were really boring, and it seemed as though the writer wanted you to go like "Wow this is so twisted and cool" when in reality it was like "That don't make no sense." Essentially, the book consisted of Amy's horrible decisions. Amy was a compl ...more

I am getting tired of Amy Cahill always feeling that she has to do everything herself to protect others. I understand why the authors do that, but I am getting tired of it. Glad the series is almost done. Starting to get tiresome.

I am going to kill Amy before Pierce does! HOW COULD SHE DO THAT TO JAKE?!?!?!???!?!? And then she was going to make things all happy happy good good and then SHE DIDN'T!!!!!!!!!!!!!! And what's up with Fiske? What sort of meds is he on?

In a nutshell: more discoveries, more clues, more twists.

Notes: I'm starting to think the unstoppable series is quite forgettable.

Was about to drop out of this series, the ending hit me and now I have to know what will happen next. Ughhhhhhhhh, good job Jeff!
This is such an improvement from the first one. More action, less pointless conversations. Best part must be the chapter in Pony’s and April’s povs. I want to know more about these two geniuses.
The thing is, I don’t know if I can stand Amy and Jake for another 200 pages. Both of them are annoying and behave in a i-know-what-is-best-for-us way.

Amy and Dan Cahill have survived, no mean feat given how many family and friends have passed on around them. But a new threat has emerged, one that has power over the media, who will stop at nothing to overthrow the Cahill’s and create his own army. And mass produce the serum to make the world his own. The challenges are greater than ever before for Dan and Amy and to protect those around them…Amy may have to stand alone before an unstoppable enemy.

Actually I'm kind of bummed. I've read all the books in this series and am self-admittedly probably the only person over 40 who has read each of them in one sitting within the first week of publication. I haven't been able to explain why I like them so much since they are the same thing over and over - how many times can Amy and Dan just barely survive and why are they so smart that they've continued to outsmart all the bad guys?

I am not sure why I still try with this series. I guess its because I sort of liked the first and then it turned into a money grabbing empire.

I can't stand most of the characters. The stories are inconsistant with the previous books. Amy just pisses me off because she's a moron who has become some love sick puppy dog who thinks she knows it all. Everyone else is just as frustrating there is Jake who is a smirking jerk 90% of the time and I just sort of want to slap him a few times to knock the
After the trainwreck that ended the last series? Why the fuck are they still coming out with more books. Not even the promise of Ian could get me to pick up this series again.
Also is that Thor's hammer?
Have we gone from 'magical elixers that sort of have something to do with science' to Thor's hammer 'myth myth fucking myth' so quickly? Christ who is writing the plots for this series again? Do you even care anymore?

This was really pretty awful. Prepare to be beyond annoyed with all the characters. The only moment of greatness was when Nellie channeled Ian. I've always been fond of the two of them (though Ian took awhile), so no surprises there. Our main characters though, particularly Amy? The WORST in this book.

The 39 Clues is a fictional story written by, Jeff Hirsch. There is now a new series, with the same people, but in a different setting. Dan is hurt and scared, he got shot and kidnapped and on top of that he got thrown into a pit full of deadly snakes, he is in deep deep trouble! Thankfully he is smart and had good luck as well as his sister or he wouldn’t have made it. There is now an even bigger threat then they had ever before, this threat doesn’t like their family at all and is using the Cah ...more
It's been awhile since I last delved into the world of the 39 clues. Like many other readers, this one fell flat for me. It didn't help that I couldn't remember certain plot points (where did they meet Pony? what happened to Fiske?) from the previous book. I miss the original series where you had so many characters from the family-- it was fun to see Alistair, and Mcintire, and quips from Grace's past. I did enjoy Nellie's small role in this story. I may continue the series, but certainly am not ...more

Ми то всичкото хубаво, ама много се разводни цялата история. Добрите бягат, лошите ги преследват, най-накрая нещо се нааква, клифхенгър... и хайде към новата книжка. Хубаво е да се къртят кинти, спор няма, ама чак пък такава сапунка не е на хубаво. Плюс това в тази книга специално има толкова много душевни терзания, че за малко да пусна сълза. Ади нема нужда. Хубавото в случая е, че книжлето е тънко и се чете за половин ден - тоест, човек не може да мрънка после, че е загубил чак толкова много в ...more

I was glad I pushed through my disappointments with Day of Doom and listened to this book. It was good, but towards the end there was a lot of similes/imagery like, "... like a fist," "as if a..." and so on. But over all enjoyable. :) Enjoy!

The Cahill books keep getting more and more complex! I don’t necessarily like the turn Amy’s character has taken but I sort of understand it. I can’t wait to see what happens next!!

Historical fiction. I love the Adventures of Amy And Dan. This series is their 3rd adventure.

Very educational. It is one of my favorite series. It is kind of the Vespers coming back to life again.
