It’s fun reading about Katie and Jake traveling, maybe they can travel to Africa where my grandparents came from.

Mary, age 9

My two favorite characters are Cooper and the Trunk…I like Madame van de Berg too.

Kevin, age 10

When I was young, I liked reading a good story where I learned something. I still do and enjoyed reading this one.

Jean Marzollo, author of "I Spy" and other books.

A mix of fantasy, mystery, and adventure with a touch of humor

Lisa Kochik, children's librarian

This adventure series offers possibilities for children to learn about foreign cultures and unusual people.

Jim Delviscio, school principal

I like that the trunk talked in poems. The poems were fun to read.

Jacob, age 11

Do you want to travel to different places around the world without ever having to leave your house? Then The Undercover Kids’ Holland Adventure The Trunk in the Attic is for you. This book was a great book. If there could be a 10 star rating, I’d give it 10 stars!

Andrea, age 10

If you like mysteries, Magic Tree House books, and books with secrets and adventures then you will like The Trunk in the Attic! I can't wait for the next one. What will Kate, Jake, & Cooper do next? Where will they go? What new places will they discover?

Susan Couture,children's librarian

I really enjoyed reading this book. It moved me and took me back to Amsterdam. I recommend this book to all who are young at heart.
