All I can say about the book it was the easiest one about the events, about Amy and Dan's itinerary and finding clue until now. But realization was worse. How they could be a Madrigal, when they two hated them so much.
Entry 1-

Amy and Dan Cahill are the protagonists and they are all on their own in the hunt for the 39 Clues started by their grandmother, Grace Cahill. They must depend on their own instincts to beat their wealthy cousins to the final product, the serum including all of the 39 Clues, which makes whoever drinks it the most powerful person in the world. The antagonists are the other Cahill members taking part in the hunt for the 39 Clues.

The setting is all over the world as the clue hunt l

Ну ничего себе, вот это поворот. Впрочем, я об этом догадывалась, но ведь фамилия-то почему такая?
Эта часть менее насыщенная событиями в отличии от остальных, но конец порадовал.

The Viper’s Nest is book number seven in a mystery series, which incorporates game cards and an Internet site that continues the adventure. This would be a great book for Haidyn to read independently. The characters are a part of an ancient family that is broken apart into its branches and is searching for a great source of power. These family branches are all racing to get this power and to keep the other members from getting it first. They must find 39 clues, which lead them to the power. I ch ...more

I'm actually reading this whole series to introduce 3 and 4th grade students to a series that discusses history and science topics that aren't covered in the classroom, and encourage them to use library resources to look for more "clues." I wrote a review of the first book and did not intend to write reviews for the rest of the series (there are 11 books total), but Lerangis' writing was actually a step above what I had come to expect. There were a number of moments where the characterization wa ...more

Oh my gosh. Here is yet another awesome 39 Clues book. I wonder how do the 39 Clues writers come up with those mind-boggling puzzles and codes topped with historical background and everything. And speaking of puzzles, codes, and history, in this particular book, readers are brought into another action-filled adventure to South Africa (Pretoria---because of the song March to Pretoria which was a clue from Irina Spasky---and I even checked out the youtube video of
In this 39 Clues installment, Amy and Dan are reeling from their experiences in Indonesia and ready to go wherever their clue takes them. Unfortunately, they don't have a lead... but fortunately, something turns up (as it always does) to help them along and take them to Africa. Lots of history lessons are given and family backgrounds are explored, including the big revelation of which Cahill branch Dan and Amy belong to!

Some of the dialogue - especially at the beginning of the book - felt forced

So a lot of stuff happened in this book, big stuff for Dan and Amy. But that's not what affected my perception of this book. I couldn't get past how annoying and whiny Amy was. In a way, it's very understandable because of what happens to them in this book. They are forced to go through a lot of things that young children should not have to deal with. All the same, I can't help but feel that perhaps it was the way Peter Lerangis wrote the book that made Amy seem so annoying.

The book was a little

I really enjoyed this installment. It was exciting and I felt immediately pulled into the story. The characters were true to themselves, and there were some great twists that left me wanting more! Can't wait to read the next one.

this book takes off the exact same day as the last book. this is kind of different because it is usualy a while before the next book starts. right now they are worried that a volcano is about to BLOW!!! Now I it is about a week later and I just finished the book. I just found out what branch they are in and i I was really supprised I did not even know that it was a branch!
Terrific, one of the best in the series. Lots of history without lecturing. Tons of action while preserving the emotional context. Witty without pandering. And lots of suspense, expanding on the mystery. Plus a heck of a cliffhanger! Thank goodness the books come out only 3 months apart. Very well done, much better than Lerangis' first book in this series.
And on the back it said Amy and Dan would find out what branch they're in, but it didn't really say. It kinda said it on the last page, but not really. And it's a little annoying how they keep changing authors. I wish they would stick with Rick Riordan...
Brandon O'Neill
An OK entry by the standards of the series. Didn't learn too much about South Africa or Shaka Zulu that I didn't know, but if it teaches some kids about apartheid, then it was good. It did make me want to watch the 80s miniseries of Shaka Zulu, which we now have in the library.

I was afraid this same author might make Amy Cahill a silly love-struck girl again. He did it to her in "The Sword Thief" but this time, even though he introduced a love interest for her, he didn't make her behave too bad. But my grouse would be: why is it necessary to give her a love interest? These are a series of books for children between 11 and 14 - give us cool action scenes, lots of them, hold the love scenes.

Lerangis's action sequences are better now. Our heroes fall in and out of scrap

The hunt for the 39 clues continues with Amy and Dan Cahill, but now they are in South Africa and they are looking for a clue about their ancestor Shaka. Together they have to use Winston Churchill's riddles to figure out where clue number 7 is. As the Cahill's scramble over each other for the unimaginable power that the 39 clues is guaranteed to grant them, they see the Cahill side of them come out.

I actually didn't enjoy this book very much. There w

A good book but definitely not the best in the series, but better than the other one he wrote. I enjoy learning what branch Dan and Amy is, which I'm not gonna say :p Overall it's was an ok book.
This series - though written for teens, is very well written and engaging... Once you start reading, it is very hard to put down... Written in the Cliffhanger style...

I have to say that I didn't care for this one.

Amy and Dan go to South Africa in this one. I have never been there but I have friends who have been and they say it is more English and Dutch and less like a safari.

Amy was very mean in this one and was just obsessed with getting revenge for her and Dan's parent's murder. Some of the things that I did like about this one was they got to work with Hamilton Holt again, they trusted Nellie, they found a new ally, they found out some more about Grace a

I think that the book was ok. What I liked about the story was how great the author described how the characters act and look. For example in the book The VIPERS NEST described how when Amy or Nellie yelled and all Dan saw was the vaine pop out a little from Amy or Nellie's neck. What can i say I kind of like the book all the detail and great action going on it's pretty cool. I wish there were pictures so I can see what's going on as of animations. But I understand it's a chapter book. Animatio

Peter Lerangis writes another book in the series, the Viper's Nest. After Irina's death in the fire, Dan, Amy, and Alistair are rescued from the Indonesian island, but are separated when Alistair is accused for the fire by his uncle, Bae Oh. They follow the clue hunt to South Africa where they learn more about their grandmother and their family. After learning more about their parent's fake I.D.s, they begin to suspect more about the branch they belong to. I recommend this book to people that en ...more

Well finally, after all this time we know what Amy and Dan's clan. *MAJOR SPOILER CENSOR BAR* OK, now that we know that they are *SPOILER CENSOR* this makes the story get more action pace, now that we now know that their parents died from Isabel because of them being *SPOILER CENSOR* and also why everyone hates them. Also just saying Irina dies from Isabel, why haven't the cops put a bounty of $50,000 for her. Also now that they know Grace is a Margial because of *SPOILER CENSOR* and also it is ...more
If I were reading these as they published them I probably wouldn't be getting tired. Back-to-back you start to get the feel of the repetitive nature of the storyline. Still some good twists and turns but I'm getting tired of the same "inner musings" of the lead characters. Also the same bad guys coming up with new ways to attack 'the poor orphans". The thoughts of the extras are great though and varying the revolting family from book to book works as well.
Worked out the clue and the family line
Adventures with Dan and Amy are so cool. Decoding messages, traveling to exotic places, learning history on the way, understanding how difficult it is to work with a sibling, etc.
The clues are so well spread and the pace is smooth yet fast. I have enjoyed every single one of the books in the series. I am glad to keep on learning more about the characters. And the turning of events always keeps me on my toes.
I'm not sure traveling the world will be any fun after reading about this kind of travel
Out of all the seven books I’ve read so far in the series, this one is the most suspenseful. The latest lead takes 14 year-old Amy Cahill and her 11 year-old brother Dan Cahill to South Africa in search of the next clue in the hunt for the 39 clues that unlock the secret to a great power.

Although South Africa does not come alive to me as some of the other destinations did, the author focuses on its history of fighting apartheid and gaining civil rights. We meet some of the late Grace’s good frie

After the fire that took Irina's life, Amy, Dan, and Allastair Oh find themselves on an erupting volcanoe and in a lot of hot water! After Nellie manages to get a boat to take everyone back to Indonesia, Allastair is apparantly (to Amy and Dan) arrested and Amy and Dan are left to head to Pretoria, South Africa on their own. Amy has noticed that she has growing "Cahill" tendincies. Dan is oblivious, but eager to track down the next clue that has connections to both Winston Churchill and Shaka Zu ...more

“Let's scope the place out," he suggested, heading around the side of the building, "and be careful in the bushes."
"Why?" Amy asked.
"This is South Africa, dude," Dan replied. "Where cobras come from. And not the hot ones, like Ian.”
“Amy Cahill didn't believe in omens. But black snow was falling, he earth was rumbling beneath her feet, her brother was meowing, and her uncle Alistair was prancing on the beach in pink pajamas.
She had to admit, the signs were not promising.”
