Dark Day in the Deep Sea by Mary Pope Osbourne is the 39th installment in the early reader series. In each book, the protagonists Jack and Annie discover, in their local grove of trees, a magic tree house that whisks them off on an adventure. Generally, they have a book as a guide and an important task to complete. This series is aimed at the K-3rd grade set.

I love Magic Tree House series! I can always count on its pattern of chapters: discover the tree house and task, begin adve More...

Jack and Annie went on a boat with these scientists and they called this thing a great beast and Jack and Annie were wondering what that was. Then there was a storm and they got tossed overboard. This octopus saved them and the ship was coming close and they pulled them up and they said you got caught by the beast. They said, "No, he's not a beast. He is friendly." Just as she was saying that they were capturing the octopus and he said,"Me Not Monster. Want Go Home."

Jack and Annie tried to tell the sailors that it was peaceful, but they did'nt listen. Then they got out thier axes, pistols, rifles and then the secret to happiness was that creatures need to get taken care of in some way

Jack and Annie traveled back in time to an island beach in the Pacific Ocean. They were picked up by a wooden ship with a crew of ocean scientists. Jack and Annie were swept off the ship in a storm and were rescued by a giant octopus. The ocean scientist gave them a giant shell. The ship took them back to the beach. If you ever travel to an island in the Pacific, you should look out for the giant octopus.

As I was reading this, I thought "all right, this one really has dramatic tension, they really do get better as the series progresses." But then MPO took out a 2-by-4 and starting hitting us over the head with it. Oof. We get it! All life is precious! But how are scientists going to understand the sea and the creatures within if they can't study it? Anyway, too much preaching. Enthusiasm balloon seriously deflated.

I am still reading my daughter's books so that I know what she is reading and can discuss it with her so that I can know that she actually reading what she says she is reading. This one is another Merlin mystery and Jack and Annie are still searching for ways to happiness. This one they are sent to the 1800's and discover that compassion leads to happiness.

it is a okay book and the main characters name is jack and annie.
it is mostley about a magic tree house and they get in it and they can travel anywhere they want to.That is if they have a book about the place that they want to go.I have their whole series of books that i got a couple years ago.Most of their books are good but this one wasnt my favriot one out of all of them.

I read my nephew's copy of this book one afternoon while visiting... not entirely sure what I think. At his age I was devouring the Hardy Boys novels, which are more complicated and fulfilling, but it's probably a good book for younger kids. It's transparently didactic at points, but there are worse sins in the world.

I have enjoyed reading these books to my grandchildren. Their eyes get big and they have learned to stretch their imaginations. Even the younger ones who would normally enjoy picture stories more, get very involved with these exciting adventures. When I come to the end of a chapter, it's "More, More Gramma, More.

Not my cup of tea, but my son enjoyed the story. I had to help him a bit in the reading, but I think he is ready for these books.

The story is very linear and a little too quick, but taking into consideration that this is a children's book, it has a decent pace, which the little ones should enjoy.

This is another good book in the "Magic Tree House" series. Our girls love Jack and Annie and we've read so many of their adventures, they are very familiar to us. This story started off a bit slow for us, but once we got into the action, we didn't want to stop until we'd read the whole book. It was an interesting look at ocean exploration in the 1800s and the addition of a talking octopus was a bit fantastic, but fun.

Very interesting! I never knew about any of this history before. I wonder if the reason no one ever captured a giant squid or could even prove they existed until recently was because of Jack and Annie's magic?

I'm obviously too old for these books, [I'm 16] but they're like a guilty pleasure. I'm rating it three stars because they are basic and repetitive. However, they're great books for little kids!

Jack and Annie learned that animals like to be at their own homes. The sailors learned that, too. It is justice to let animals stay in their home because they are due to be treated kindly.

These books are so hard to review.

Predictable, perhaps a bit scarier than most (if you have a child that relates to animals). My 6yo liked it just fine.

I liked the pacing of this story ... I wasn't previously familiar with the historical figure featured therein, so I learned something!

I liked this book. There is a giant octopus and it can speak. My favorite part was when Jack and Annie went into a man's sea lab.

This book was good, but it had some parts in it that I thought was very boring. It's still a very good book just not as good as the other books I have read .
