It was a very cool book because everybody turned into seals and the next book was about the ice wizard and this book was a little too.

the seals in the story was soooo cute and getting the sword and helping the magician was also cool


this was a seal of fun.

Great Series

The Magic Tree House series brings back so many great memories. I remember reading these books when I was in the third grade and they were my favorite books. Everyone in my class was so into these books, they wouldn’t let go of them. These books are action-packed, full of adventure, filled with astounding twists and turns, and sometimes give the reader a nice laugh. Not only do they entertain the reader, but they also give tons of information about history. The storylines aren’t all that bad, either. I think it’s a nice way to educate our young ones. The series is a very interesting mix of fiction and nonfiction. Sometimes, I even find myself skimming through the books just for a nice, quick, twenty-minute read. I bought a few of the books when I was younger and now I’ve passed them on to my younger sister. She not only loves the series, but she is determined to read the entire series. I also appreciate the fact that the author, Mary Pope Osborne, is still writing books in the Magic Tree House series. Each book is a simple chapter book, ranging from seventy pages to one-hundred twenty pages. I would definitely recommend this entire series to anyone from kindergarten to fourth grade (based on the individual’s reading level, of course).


i love it

Merlin Missions

This book is one of the first merlin missions, and one of the best!


Jack and Annie (brother and sister) discover a tree house that can take them any place in the books inside the tree house. They meet Morgan, the owner of the tree house, who is a magical librarian. In each book, they are given a puzzle to solve and a reference book that helps them. They explore science and history in the process of solving these puzzles. Some of the books were a bit scary for my kids. Generally, Jack and Annie work well together but there are times when Annie makes poor decisions that get them into trouble. A good way to sneak in some teaching in a reasonably entertaining and inoffensive manner


The cover illustration is great.....Jack and Annie are once again off on an adventure!


I liked the sea serpent part.
