I love the mythology! What a fun way to introduce kids to selkies and King Arthur's sword and more. Plus another very exciting transformation (ravens and flying in the last book) into seals swimming in the sea. Such a great fantasy at any age, who wouldn't want to try that?

Sometimes these kids seem impossibly wise. On the other hand, sometimes things come out of my guys' mouths that are so sweet and perceptive that I am truly humbled. Maybe reading stories like this helps that along.

I'm not going to rate this as I didn't read all of it as my mother read the first half to him. What I read was enjoyable though and my son loved it. He just brought home #37 last night and asked if I read these when I was a kid. Never heard of them. I think he might finally have the patience for Harry Potter now though :)

The mythology in this is incredible, the way it connects to Arthurian legend. Jack and Annie have the most spectacular adventures, and just when you think they've done everything anyone could possibly do, from riding tpteradacltes (don't know how to spell it), to acting in a Shakesperean play to turning into seals to surfing in Hawaii, Mary Pope Osborne dishes up even more, such things you've forgotten to consuder what could happen in a magic treehouse.

I liked this book because Teddy and Kathleen helped Jack and Annie with their mission.

Last semester, I was introduced into the Magic Tree House series, but I never finished an entire tree house book with a class. I loved that at the end of each chapter, they left cliff hangers that kept me wanting to find out what would happen next. I also felt like the descriptions were vivid enough that I could imagine myself there. The few illustrations throughout the book also kept my attention. I really did enjoy reading this, and I'm sure I will find myself reading another one from the Magi ...more

I think this is a great book for kids ages 6-10 (depending on reading level). It is about a boy & a girl (all kids can relate to one of them) that go on a quest. They must follow directions, make choices, and be careful. The descriptions are easy to understand and have just enough vocabulary words to challenge the children. As Annie & Jack move "Onward" the reader also gets to learn new things. This book I learned what a Selkie was. I have never heard of this mythical creature before so ...more

My 5 yr old is becoming a voracious reader and his teacher recommended this series so I picked up a few from the library. My son loves it. Magic and fun and adventure rolled into a chapter book that's easy to read, yet challenging enough that he's not bored. We just started the Pizza Hut book it challenge where he has to read 240 mins a month and then he gets a free personal pan pizza. He's loving it, and already has said these are the books he wants to read for the challenge. Overall a great st ...more

Not bad. This is actually my first experience with Magic Tree House books. My 1st grader thought it was amazing. Lots of action and absolutely no waiting for it. They used some good vocabulary as well. As I said, not bad.

I like this book because in the book it states, In a land lost in mist, in a time before time, there is a powerful Sword of Light. Now Merlin the Magician needs that sword for the good of all Camelot. He turns again to Jack and Annie for help. And again, Jack and Annie take up the challenge!(pg.1) I also like this book because this book is A MERLIN MISSION book, I know that because in the story it states, Summer of the Sea Serpent is the third in a special group of Magic Tree House books called ...more

For a little while now we haven’t read any Magic Tree House books, but last week my son brought this one home from the library at his school and this week he brought home another one so I guess he is ready to read more of them! I’m glad because this is a series I can really get into and that I enjoy with them, more so than some of the other chapter books they’ve self selected at library. If you are unfamiliar with the characters there is a prologue to help you jump in, but basically Jack and Ann ...more

This book is the third of the Merlin missions. It occurs on the summer solstice, the longest day of the year. Jack and Annie are given this poem by Merlin:

...Before night falls on this long summer day a shining sword must find its way into your hands and out of the gloom--
Or Camelot's king shall meet his doom. To begin your quest for this Sword of Light,
Call for the help of the Water Knight. Then pass through the Cave of the Spider Queen.
And swim with a selkie clothed in green. Enter the Cove of

The Magic Treehouse books involve two children, brother and sister Jack and Annie, who are able to go back in time in their magic treehouse. The stories revolve around the adventures the children have while time traveling to places and times they have read about.
In this book in the series, the children are directed by Merlin to go to England in the time before King Arthur and Camelot. Their task is to find the Sword of Light and they encounter a variety of real and mythical people, magic indivi

From underwater caves to a Spider Queen, from mystical selkies to a magical sword, this is a Magic Tree House adventure kids won't want to miss."

My Review: If you saw my review of the previous book in this series you will note that I felt like Jack & Annie hadn't aged enough for the time gap, well Jack certainly seems to be growing up

As both Jack and his sister Annie travel to a unfamiliar location they are given a mission by Merlin to complete along with limited magic spells. Along with the mission the biggest obstacle is to defeat the monstrous serpent in order to rstore the ba

A pleasantly surprising find in this uneven series. The intermingling of selkie lore with Arthurian magic is satisfying, and Jack's characteristic grumpy trepidation is paid off nicely when he must choose between responsibility and a powerful transformation.

In general, I think Jack and Annie's adventures into the mythological and legendary work better than their romps through facts of history and science. I understand the utilitarian appeal of books where readers Learn Stuff, but Jack and Annie'

This was one of the more epic of the Magic Treehouse books, as Jack and Annie retrieve the sword Excalibur (!) for Merlin. It also introduces Kathleen, a selfie who will go to be a recurring character along with apprentice wizard Teddy.

I read this with my seven-year-old son, who has become quite the Magic Treehouse fan.

Jack and Annie face a series of challenges, including a magical water knight, a giant spider, and the mighty sea serpent, who is a frightening and powerful adversary for the kids

So adventurous! So Exciting! So Scary!

This book had the refreshing coolness as an ocean spray. Which is something because Jack and Annie are all over that type of landscape.

This adventure was fun to learn about because as awesome as all the action and mystery is, the history and facts are something to be learned here. I can see how inspiring the words are and the thoughts provoke the mind because of them and the beautiful scenes that emit from such master craft.

One thing I did notice, was that M

"Summer of the Sea Serpent" is book number 31 in the Magic Treehouse series, and just as enjoyable as the other books in the series. My 5 year old checked this out of the library at school and read it alone, then we read it together with his 8 yr. old sibling. I enjoyed the story as much as they did. and recommend this series to other parents as a lower grade introduction to mystical, magical, mythical reading books.

Jack and Annie went to a time that was a myth. THey went to a place where there were seal girls that turn into seals because they are selkies. They can also turn other people into them too. They even have their own language too. They can swim past a lot of jelly fishes because they are seals with rough skin. If they lay in the sun they will be able to turn back to normal.

Jack and Annie had to find the "Sword of Light" or known as Excalibur before nighttime. Merlin was also a water knight with a

I read this on request of my son, who is absolutely enraptured by Mary Pope Osborne's series. Though by my typical reading standards, it doesn't necessarily match up to others that would receive this rating (Charlotte's Web, The Tale of Despereaux, Where the Red Fern Grows, etc.), any literary work that captures the interest of my kids, to the extent they will spend hours at a time absorbed in reading, will always get five stars from me.

Now please excuse me while I go have a book club discussion

This was the third "Merlin mission" book in the Magic Tree House series and although our girls were scared by the mean looking sea serpent on the cover, they really enjoyed the story. There were some scary parts, but Mary Pope Osborne did a good job of not taking it too far, making the Spider Queen nice and the sea serpent an honorable creature. We are looking forward to the fourth book in this mini-series; I am amazed at how quickly we've read through more than 30 books in this series and our g ...more

My son loves this series.

Jack and his little sister Annie are two regular kids from Frog Creek, Pennsylvania... until they discover a mysterious tree house full of all sorts of books. From that point on their lives will never be the same again! They soon go on amazing adventures (plus children are learning bits of history and most don't realize it) as they travel through time with the help of the magic tree house. The chapters are short with pictures every few pages, making these books perfect f

Full of magic and excitement. My children, ages 5 and almost 9 both loved this book. The Merlin missions so far have been to imaginary places, so they unfortunately don't have any real facts and history in them like many of the other books. Often these books, having some real facts in them, have led to new topics of study for my children. However, these Merlin missions, being all imaginary haven't done that. But, my children have enjoyed them just as much. The magic is wonderful and captivating ...more

I read this aloud to my girls (5 and 3) and while it was a little above the 3 year old's head, my 5 year old loved it. This was our first Magic Tree House book (my 5 year old just HAD to start with this one--hopefully she'll be OK with reading #1 next) and I thought it was great. I love that the author adds in mythology and legends from different countries and cultures--and that she has an author's note at the end explaining where she pulled everything from. It was great to read a book that is e ...more

Jack and Annie had to get the sword of light which was buried under the sea. Along the way they had help from The Water Knight, The Spider Queen, Teddy and Kathleen. As soon as they got the sword the sea serpent came and asked them a question. When they got it right the serpent fell into the sea. Teddy and Kathleen helped Jack and Annie get back to the treehouse. I liked this book because I like sea serpents - I also liked when Teddy, Kathleen, Jack and Annie transformed into seals to go through ...more
