My second grader loves these books. Never could get them to read, they enjoy this series and continue reading. I recommend this series for anyone.Love the concept and originality of introducing young kids to history and cultureI bought the first 4 books in this series for my 6 year old granddaughter along with another dozen or so books. She became very excited about the Magic Treehouse when her first grade teacher gave the class the first book for their reading lesson. She already had her very own copy and couldn't wait to get home to read it. She read the first 4 books in a week and loved every second of it. She came over and brought a book and read it to her grandmother and I. We were so proud of her progress and even better, she was proud of herself. I immediately purchased this ultimate box set and she has been reading about 5 books per week ever since. She's had tests in school about her comprehension of the books and her scores have been perfect. Her teacher has been so impressed with her reading that she has been given several class awards and they tell us she is reading at third grade level now. It's all due to the Magic Treehouse books. We've since purchased Magic Treehouse books that have been published after this set came out so she has #29 through #33. We also got her the Magic Treehouse Merlin set as well and she will be reading those this summer. She has learned so much and her proficiency is now better than we ever expected. She is telling her cousins all about the books and has given them the ones she's finished so they can read them as well. Learning is great for kids this age, but the joy and excitement for learning is priceless. I recommend the Magic Treehouse books as highly as I possibly can! They are a definite must have for your early reader.I ordered this book set for our grandchildren. When the last day of the promised delivery days passed and the order did not come, the tracking said sorry the order is late and it stopped showing where the package was. The book seller contacted me after I reviewed my order as not receiving it. The seller was very caring and offered me a refund or replacement. They contacted the shipper, USPS, and told me to wait at least 48 hours while they try to get our package to me. It came within 48 hours thanks to their efforts to help me get the books for our grandchildren who love the series instead of just taking the quick and easy way of refunding my money. The seller's price was good. The service was good. The follow through was great and flexible, not restricted by computer programs.The print is of poor quality, however seller was responsive and helpful.I bought the first 8 Magic Tree House books for my 7 yr old grandson and he loved them so much that I've now purchased the first 29. I've also purchased the Merlin Missions boxed set for his upcoming birthday. He was a great reader before receiving these books but now he gets excited for reading time. He can't wait to read the next adventure. This collection is helping to create a true love of reading at that very important young age. I'm thrilled with the books and the author!My son is 6 and is flying through these books, he reads 2 chapters a day. Amazing.Bought for my Granddaughter for CHRISTmas and What I liked about it was my Granddaughter loved them at the age of 9 and read all the 28 books! Now a month later, I am looking to buy her another set of books!!purchase is not received. I would never order it again. nothing recommendable
