Read for my son as a review for his Advanced Reading test tomorrow. It’s a fun action and adventures read. A brother and sister exploring trip in the Amazon rainforest. They travel using the magic tree house and a book. During their travel in the new place, they often refer to the book for info. They encounter problems and figure out solutions. Their trip are for a mission. Highly recommended!

Another great grand adventure. So many details about the animals at the Amazon and the Rainforest.

We’re continuing where we left off in the last novel as Jack and Annie continue to look for the things they need in order to help Morgan. This adventures takes them to the Amazon where they learn about so many different animals (some that I spent time looking up myself). These books support/nurture growing readers and don’t necessarily have the most substance. To me, they’re quick and enjoyable in their own way. I’ll be looking forward to picking up the next one.

I said in my review of "Sunset of the Sabertooth" that I loathe these books, so I'm not going to say it again here. Logan actually didn't like this one so much as it fed his already growing fear of dangerous wildlife. And I find that a lackluster story interspersed with a wooden main character reading aloud from a reference book isn't really the way I want Logan to get his facts. In a 67-page story, here is what we got:
--The Amazon rainforest is hot & steamy, has a lot of plants, and is made up of three layers: the floor, the understory and the canopy.
--When an animal blends into its surroundings, that's camouflage
--Flesh-eating army ants march in hordes and eat flesh.
--The Amazon river is over 4000 miles long.
--Piranhas will eat anything, even people (seriously, that's all the info we got.)
--Green snakes look like vines. No name for the snake though.
--The jaguar is the biggest predator in the Western hemisphere.
--Vampire bats suck blood at night. Again, that's all we got. Only the scary part.
--Mangos taste like peaches.

These facts are so random, short, and without context that they aren't really more than memorizing trivia. Yep. I'm not too impressed with these books.

Another banger! Quite a dangerous adventure out in the Amazon! Lots of creepy crawlers! I love reading these in order and seeing them all connect and tell a pretty cool overarching story.

Jack and Annie are still on their quest to find 4 things in order to break the spell that the enchantress Morgan le Fey is under. This time, the object needs to be found in the depths of the Amazon Jungle. Danger lurks around every corner! Jack and Annie encounter Snakes, Marching Army Ants, Jaguars and many other creatures along the way. Will they find the second object? Will anyone help them this time? This book is full of adventure and danger. A must read for all Magic Tree House readers. =)

****3.5****

It was one more fun ride with Jack and Annie. Duo of Brother and Sister are on to another adventure in the forests of Amazon where for the first time Annie is scared. We meet the different animals and also kids succeed in finding next object that will help them to rescue Morgan!!

I just wonder how my kid is able to connect with these stories so fast and he remembers the back stories too. I tried with some other kid's books which were not so great for him and he used to loose interest in middle...

Happy Reading!!

Pretty uneventful, but well-paced enough and with an important enough goal that I didn’t mind. I also loved the lessons the children learned about rain forests and the importance of preserving them.

(PG rating)

Fun book! My daughter loved it. A quick adventure in the Amazon with a brother and sister. They are trying to find magic items to free Morgan Le Fay from her magic spell. My theory is Morgan is the mouse 😅

I have to keep reminding myself that the target audience is very young and these books are more for getting kids reading than teaching facts and information. 3 stars

Really cute, and obviously a quick read. Bought a few at a yard sale when I was feeling nostalgic and impulsive and needing to meet my book goal lol

I enjoyed this book because I liked the part when Jack and Annie got to the other side of the Amazon river in the Amazon rainforest. I did not like this book because I do not like crocodiles, jaguars, and monkeys.

My son is on a re-reading spree. He could read them himself, but he still likes them for bedtime stories. This one is quite harrowing, given that the Amazon rainforest is filled with dangerous animals at every turn. But the kids prevail and find what their looking for, but not without the help of a "native". My son theorizes that the helpers in this mini-series of 4 could be Morgan herself. But I countered with logic (and it actually was acceptable to my son!): if she needed help because she was under a spell then how could she transform herself into various other people/animals but not back into herself? He said, "Oh, right".

In a book slump, so I’m rediscovering the series of books that made me fall in love with reading many many years ago. Thanks mom for keeping all my magic tree house boos and for continuing to collect them as they come out.

This was a great adventure. I love how these stories give empowerment to kids. With thought and effort, they can overcome anything.

One of my 4 main reoccurring nightmares in childhood was on being on a boat in an Amazon type river. As we travel down the river a croc eats the boat and lifts it up Jaws style and I slide into his mouth, awakening just before death.

After seeing this cover art for the book for the first time in 20 years, I see that this may have been source material for said nightmare.

My lawyers will be in contact.

Good story. Good scenery. Would have liked less beastiality

My son and I loved how many animals are mentioned in this book. Right after we finished, we took out more books to look up all the creatures in rainforests. THIS is exactly why we read together. I love it!

Read with my class. As far as Treehouse adventure goes, this one was just missing something for me. Like it felt like this one just sort of went through the motions. A "mango" being this adventure's objects seems random but I guess in context each adventure constitutes a day so it maybe wouldn't rot before the end spell can be enacted.
