The plot thickens, and the adventures are more and more dangerous. Some intriguing new characters appear. Too many coincidences in this book.
I have an assumption about the Madrigals and I really want to know if I’m right or not.


"There is Rakata."They could see it now, the island with the volcanic peak of Anak Krakatau, the child of Krakatau. Dan felt a chill along his spine.
It must have looked similar to this when Robert Cahill Henderson first arrived. It was flat on top, and the white smoke was mixed with gray. Dan heard a rumble of thunder but hardly registered it. He was too much in awe of the sight in front of him. Somehow you could feel the power of it, of how much boiling energy was contained inside. Even though he'd pretended not to listen, his brain couldn't help but record the facts Amy had read to him back on Shep's plane: 36,000 people died, mostly in the tsunamis that followed the final explosion on August 27; two-thirds of the island was blown away; the final, massive explosion was heard more than 2,000 miles off; shock waves circled the earth seven times; the ash cloud was propelled upward for fifty miles and circled the globe for thirteen days, eventually creating amazing sunsets throughout the following year. All the numbers added up to one bad volcano.

Australia has too many poisonous species for me.

Following the trail of their parents, Amy and Dan arrive in Australia. They meet up with their long-lost uncle, Shepard Trent, carefree surfer completely unaware of the hunt for 39 clues, the end of which will make someone the most powerful person in the world.

Amy starts to remember the last night she saw her parents alive. Could her memories unlock the truth to what happened to her parents, and who killed them?

Why would Hope and Artie Cahill go all over Australia, if not to find the Ekat who almost succeeded in finding all of the clues and putting them together? And what does it all have to do with Amelia Earhart? Could she have been a Cahill, and worse, a Madrigal? Who are the mysterious Madrigals? The only clue they have to them is Grace's last message: Beware the Madrigal.

This trip almost breaks apart Dan and Amy because of all the secrets that catch up to them. But who is Nellie? Is she keeping them safe? Or is she a spy for another family branch, planted to slow them down?

To był naprawdę dobry tom! Fakt, że akcji jako takiej było tu raczej niewiele, ale w żadnym wypadku nie było nudno. Dużo dowiadujemy się o rodzicach Amy i Dana, poznajemy sporą część ich historii i prawdę o dniu ich śmierci. I kurczę, czasem żałuję, że te książki są takie krótkie, a z drugiej strony nie mam czasu się znudzić. Już nie mogę się doczekać kolejnego tomu i jestem coraz ciekawsza, jak to się skończy, bo robi się coraz lepiej :D.

As they went on the clue hunt, the next stop was Sydney, Australia, but not Australia. It was just for misdirection. As usual book and events begins in a complicated range, so many places and so many people. It only gave clearing when it reached the end. Yet some parts needed still explanation unlike the previous books.
Also some parts made me totally confused. Thinking of Nellie, and also their dad's cousin Shep, I thought All of them, with Amy and Dan, would end up as a family. Like in the one of the previous books mentioned, I thought Nellie was the only one to whom they could trust. However, she turn out to be a secret person, or Madrigal, or someone who wants to stop them. On the other hand, somehow I remembered Alastair, and thought he stopped the chase. At the last chapter it they found him at their destination, with and Ekat stronghold, and stole "the poem" from their parents and caused their death long ago.
Simply put, Everything turns into a mess. This chase requires two things: find clues and trust no one.

Amy was better in this book. A lot stronger I think.


(spoiler)

Jude Watson I hate you for killing off Irina. She was always my favorite villain of this novel. And to make her death so damn heroic.

(end of spoiler)

But this is one of the few 39 clues book in which I actually got what was happening. A few books in the series were not capable of giving me that.I found this book quite satisfying.

The 39 Clues: In Too Deep was written by Jude Watson and this book is by far the most well-written and my favorite out of 6/11. So many surprises in just ONE book. This is getting more exciting. I can't wait to finish this series.

This series is so far really good. I love how the secretes are placed through the story in each book. This book was as thrilling as the books before. I can 💯 recommend it!

Wow. Wowowowowowowowowow.

What is up with these authors enjoying torturing me?!

Lemme take some deep breaths...I can't believe what Jude Watson did in this one. Seriously. SERIOUSLY?!

I think this one, out of the previous ones, was the best written. It's between this one and the first one by Rick Riordan. Both of them delved into the emotional parts of the narrative as well as giving you a grand picture of just how dangerous this clue hunt really is in the story.

Isabel "Cobra" is evil. EEEEEEEVIIIIIIIL. I was hoping maybe she'd turn Ian around and help him sort out his feelings for Amy, but nooooooo. She had to be EVIL.

And Irina. Oh my land. I don't think I can even talk about her anymore.

Okay...I'mma just go cool it, maybe start the next book. But first, I'll probably be doing this:




How could a "kiddie" series make you have so many feels? How could I get so attached to who I thought was an enemy, and was until the end?

I really need to stop.

There was so much more character development in this book than in all the others. It was person-driven rather than plot but that came off naturally. I actually found myself liking Irina, or at least sympathizing with her rather than hating her. I'm so glad Alister is back. And Hamilton is becoming increasing helpful. Jude Watson has been the best writer so far. And what is with Nellie?


Australia was meh. Big spiders so ew, but that's about it for Australia. It could have been anywhere.

Ez a rész egész jó volt, két dolog viszont eléggé idegesített. Lehet nem a történet hibája, hanem az enyém, de sok szemforgatást kapott miattuk.

SPOILEREK



Probléma #1 – A gyerekek szülei egy tűzvészben haltak meg, amiről azt mondták baleset volt, de nekem teljesen egyértelmű volt, hogy nem. És amikor ez „kiderült” annyi dráma jött köré, pedig szerintem lehetett előre látni, hogy ez lesz. De ezzel még mindig kisebb bajom volt, mint a másik dologgal.

Probléma #2 – Amy önhibáztatása. Szerinte ő miatta haltak meg a szülei, mert hat évesen annyit mondott, hogy „koala”. Úgy, hogy fogalma sem volt még semmiről. Ezen jobban kiakadtam. Szerencsére az öccse megmondta neki a végén, hogy hülyeség volt ezt gondolnia.

Even though much of what is written in these books is fairly absurd, I have really enjoyed listening to the saga progress. And now that I've finished the sixth book in the series, I am interested in getting through the rest of the series.

I find it fascinating to hear how each 'guest' author twists the tale and continues the plot in a fairly seamless, yet individualistic way. This book takes the reader down under as well as to other islands in the Pacific Ocean, in the process of uncovering more clues.

I won’t lie I’m surprised at how in-depth this storyline is getting for a middle school age level series. Also sad to officially be over halfway done.

I like the 39 Clues “In Too Deep” by Jude Watson because of the new characters they introduce and all the intense situation in each book. This is number six in the series.
Dan and Amy competition is getting bigger and harder to beat.

Dan and Amy are starting to learn more about their parent's past.Since their parents deaths, Dan and Amy are getting clues that they hid prior to dying. Amy and Dan are traveling under false Australian passports. They have to meet ground transport when they land in Moscow, Russia. But they wander through the airport to see if anyone is following them. Natalie and Ian check into observatory hotel so they can spy on them.

Dan and Amy opponents in the competition think a 11 and 14 year old ruling the world was a little ridiculous.They don’t want Amy and Dan to win. Dan and Amy find a clue carved in stone on a rock. They also remember that Grace’s lawyer Mr.McIntyre said, “never trust anybody in this competition only trust yourselves”. They are finding this true.

This book 39 Clues “In Too Deep” takes place in modern day Russia. Where Dan and Amy find three clues that will lead them to their next country. All of these books take you to different countries. It is interesting to hear about different cultures.

The theme for "In Too Deep," is for every problem there is a solution. You can always find answers to most problems in life. Dan and Amy did this by using their resources for solving all their troubles. They couldn't just count on other people. They had to use things they had with them and it worked out pretty well.

I would recommend this book to anyone that likes adventures. Also if you like series books. These books have people that get into dangerous situations which keep you hanging on. They are great for seventh grade and up. They are short stories but good.

I'm going to give a generic review of the series. Basically because I'm lazy and don't want to write 39 reviews. Okay, 11.

We finally read Book 1. And then because we liked it so well, the entire series. One son (age 12) has read them all, the second son (also age 12) is on Book 2. And son #3 (age 8) will be starting as soon as he finishes his current book.

I thought the premise of this book very interesting. I loved how they integrated history and geography along with problem-solving skills and code cracking. Add in the action, humor and intrigue and kids (and some adults) can't put them down. All three of us that have read 39 Clues thought Book 2 the weakest of the series. But as one son said, after finishing the series, "Gordon Korman seems to be getting better. I think he's a decent author now."

Some of the books are better at teaching the history part, others just barely skim the surface and you don't really learn about the person they're 'highlighting'. I appreciate that they're clean books - no curse words or you-know-what going on. There is some violence (very little, if any, blood) and several murder attempts, but they never work.

The series would most likely be called twaddle by my Charlotte Mason friends. I do, however, think it has more redeeming qualities than most kids literature and I'm happy to see my boys devouring a book every day or so.

The book 39 clues is about a girl Amy and her younger brother Dan head to Australia. to go discover what their own mother and father knew about the 39 clues. while on the adventure Amy is reminded of memory's of her child hood. While on there adventure she will start finding out more about her parents. The 39 clues is a challenge of a group of people the have to find the 39 clues. If you do you will become the most powerful person to the world. But is you fail you will still walk away with one million dollars.

The best part of the book is in the middle of the book. Because it is the first time in the book that you are on the edge of your seat. It is when Amy is waiting for a meat up with her and Ian which called the night before and sad that he had information regarding her parents murders. The meat was spose to be across the bay from the Sidney opera house in the middle of the day. But while she was waiting for him in the door way of a shop suddenly her enemy / compeer Isabel walked up behind her. And she couldn't run away because she had her finger on her neck and the only reason she was scared is because her finger is poisons if she pulls her finger back it will kill her. but the only reason she wanted to talk is because she knew she was being set up by Ian. And at the end they became team mates.
The one thing I think that they need to fix is the beginning for the book. Because at the beginning it takes almost a quarter of the book to start to get interesting and I love books that are adventurist and have a lot of action in the to make the book not be boring. Also a thing they need to work on is the story line in the beginning. Because in the first 30 pages the book is all over the place and you cant be on one topic.

Over all I love the book and I recommend reading this book is you are interested in adventure books or moves like karate kid or action moves like fast and furious. Because the story starts out in Russia and eventually goes to Australia where they go on a plane ride around the outback and go surfing and all kinds of other active activity's. so if you like this genre of book than 39 clues in too deep is the book for you and I would recommend going and reading the hole serious of 39 clues.

This book was mainly that sometimes the reward is worth the risk. In this book and series the reward is nothing short of the chance of world domination, the reward making you the most powerful person in the world. Now they are in Australia, and with the help of their Uncle Shep, who they haven't seen since the death of their parents, they uncover more clues while avoiding the Kabras and the Holts. They go through many dangers and as usual dodge death many times. But they still stay in the hunt, showing time and time again that they think the rewards of the hunt are worth the risks for them.

My opinion on the 39 clues is that the author is the best at wording the book. He/She used the words like sacrificed or like clutching. The author even added great punctuation because he/she put periods,question marks and exclamation points in the most unique places he/she did not just put periods in all of the end of each sentences. When I started to read 39 clues it was like a whole new world entering my brain I could not put it down I was like so into it. The book 39 clues was so good I wanted to read more but first I had to finish this whole book


I recommend the 39 clues to readers that adore mystery books because it has lots of wonders. The thing i love the most is the way the author is wording it. The setting of the story is in the current time and at the airport in the bathroom stalls. But they are exploring through the ocean. This book is also perfect for kids that are in the middle level.

I devoured this sixth installment faster than I have literally any of the others in this series, Jude Watson understood the assignment and ran with it! All the intensity, lack of stakes and sense of thrill I’ve been hoping for in the last few novels were finally delivered here and I couldn’t be happier. Maybe it’s the fact that this is in a sense the hump of the series but I really feel like it’s about to start ramping up and I really hope I’m right.

This is one of my favourites by this saga so far!
Jude Watson did her magic again.
On of the thing that I prefered was learn more about the past of Amy and Dan's parents, but I also like learn more about others characters we know yet, like Irina, Nellie, Isabel Kabra...
oh, and yes: my ship between Amy and Ian still be here... I will start the seventh book right now!

This book went a step farther than all the previous ones. We've got:
-Isabel Kabra being actually unhinged
-Finding out Dan and Amy's parents were murdered
-The true beginning of Ian and Natalie's character development
-The conclusion of Irina's character arc :(
-Nellie being lowkey shady

Honestly? From this point, we're in the endgame now.

O melhor até agora, tudo o que faltou em Além do Túmulo a Jude acertou nesse. Teve aventura, perigo de morte (mais de uma vez), personagem novo maravilhoso, novos inimigos em destaque, velhas alianças, grandes revelações, foi tudo. Gostei demais de como a história evoluiu nesse, fiquei presa o tempo todo e a leitura foi muito fluída. Expectativas para os próximos: fogo no parquinho.
