Oh lordy, after finishing the first series, I STILL don't get why it's soooo good! Especially with it being a kiddie series and...well, I'm not a kiddie...

This book was a GREAT and FANTASTIC start-off for "Cahills vs Vespers".

Things I love about it:
1) The Cahills are getting along in a "family" manner without the possibility of unexpectedly stabbing each other in the back.
2) The Vespers are delightfully sinister! I love them! They add more suspense a

It said about 2 siblings who are the members of the most powerful family in the world, the Cahill family.
When 7 of their relatives are kidnapped they got to do whatever Vesper One say to get them back. One mistake, one will die.

Just read the synopsis. Dan is 13? Two years passes eh? Doesn't that mean Amy is 17? Whoas, hard to imagine man. can't wait to read... though I have to read Vespers Rising first ^.^

2.5 stars. The extra half star to round it up to 3 is for the sheer fun the previous books were.

Not quite the page turner I was expecting. Oh, it was action-packed alright, but it somehow felt a bit lackluster compared to the previous 39 clues books. Where's Riordan when you need him?!

Amy and Dan are, once again, racing against time - this time trying to save the lives of seven of their lot who have been kidnapped by the mysterious Vesper One. He/she needs Amy and Dan to steal certain priceless

Such a good book! Loved the previous series, this one is so far even more exciting. My son was worried about Gordon Korman being the author because his school MADE him read "Schooled" this summer, and he felt that was extremely preachy. He hates preachy. No time for preaching in this book... it moves really fast! I read it on a plane so it had my undivided attention (except for the soda my daughter spilled, and then my son... and then ME... Yes, we have the klutzy gene.).

Это просто одинадцать из десяти. Черт подери, они привзошли мои ожидания. События этой книги разворачиваются спустя два года, после событий 11-й предыдущего цикла. Герои очень изменились, за них теперь жутко переживаешь, больше поражаешься и задерживаешь дыхание чуть ли не в каждой главе. Помимо Эми и Дэна, в книге фигурируют и другие Кэхилы. Они, правда, мало изменились. Впрочем, это не мешает им хранить прежнее обаяние, особенно младшому поколению.
Если честно, я не ожидала что будет так круто

This book is about two children Amy and Dan who must save their family from kidnapping but what will be the ransom. I like this book because it has a lot of action and drama just what I like and the story is so fascinating. I would recommend this book to my brother he likes these types of books and will enjoy it.

Dan Brown meets Spy Kids. For something aimed at teens or tweens, it was interesting. A quick, breezy read. I'll probably catch up with the rest of the series in between bigger, weightier books.

I just finished listening to this first book in the second 39 Clues series on the way back from a trip to Pennsylvania this weekend. I find audiobooks are a wonderful way to pass the time in the car, and books that are action-packed like the 39 Clues are especially riveting. The story kept me awake as I drove six hours in the dark.

That said, I'm losing some of my enthusiasm for this storyline. Now Dan and Amy Cahill are having to band together with some of the very relatives who were trying to

You never quite know with this series what you're going to get book to book because the authors change, but I thought this was one of the better installments. I liked the slightly more mature tone, it was appropriate after everything these kids have been through to acknowledge that they're pretty traumatized and to deal with that. But it's still simple enough for younger readers as well. it's still a bit silly, the idea that these kids could rob a major museum with a day of preparation is just ...more

Get ready for another action packed installment of the famous 39 Clues series. You thought our heroes Amy and Dan were done after discovering the secret of the 39 clues? Well guess again. This new series is very exciting, with loads of suspense and mystery thrown in. Cahills are being kidnapped by an evil organization called the Vespers. Amy and Dan have to follow the Vespers demands or the unthinkable will happen.

Amy, now seventeen, is stronger and smarter than ever. Amy is amazing as she quick

Dan and Amy have to rescue seven Cahills who have been kidnapped by the Vespers. The two travel to Italy where they have to steal a Caravaggio painting called, Medusa, from the Uffizi Museum. The clues lead them next to the Colosseum in Rome.

Book one is vague on plot. It isn’t clear why the Vespers kidnapped that many people. I found this novel less funny, less believable, and more violent. Amy has a boyfriend and Dan is more serious. Dan also betrays his good friend which I thought was out of c

The Medusa Plot was a weird read. I liked the story, and I really enjoyed most of the characters, but I didn't understand what was going on. It seemed like this book had a very cool concept behind it, but nothing was explained throughout the whole book. I loved the concept of different families with different powers, but I just didn't know who was what. Maybe I skipped that page by accident? I liked that it had kids with special abilities in it, the story was not as serious thanks to that. I did ...more

Once again, Amy and Dan are off on another adventure. Many of their crazy relatives, who have now become friends, have been kidnapped by the mysterious group the Vespers. The leader of the group have sent Amy and Dan on a dangerous mission, threatening to hurt or kill the hostages. Join Amy and Dan as they do crazy things in this book following the 39 clues.

I gave this book a 4 star rating because even though it had and excellent idea for a plot, I did not like how much the characters have chang

This book is AMAZING!!! It takes place after the first series. Amy and Dan thought they won the clue hunt and that their lives would be normal. But they were wrong. Now 7 Cahills have been kidnapped worldwide. Amy and Dan have received a package that contains a cell phone with one text message. "We have hostages. Do what we want or they die". This book keeps you reading until the end. I recommend this book to people who love mystery/detective fiction stories.

It was a good book.... Will write my full review later. Just bought it from the book store. No, not in Vietnam, they don't sell that, in Australia, exactly.
I must said that I have always like the 39 clues series. They were hilarious, full with action and adventures, a little bit romance, and classified secrets.
But the medusa plot was a little disappointed. I don't know why....

My son really enjoys this series so far. We read it aloud to him at bedtime. I do find the writing style is sometimes hard to read and I find myself adding words sometimes to make the sentence structure fit etc. But overall a great series so far.

I'm very unsure about the premise for this series. So basically some Cahills were kidnapped by the Vespers and Amy and Dan are now forced to do tasks for them, retrieving treasures around the world. I thought that this war between the families would be more like a competition to get those treasures, or trying to find some lost treasure that's connected to the mysterious Cahill ring Amy has. If they're doing tasks for the Vespers (they're being blackmailed), this can hardly be called "Cahills vs. ...more
