Mixed feelings about this one...
I liked this book, but was disappointed by the lack of color in the pop-ups. I want my reindeer to be brown, or even red--not paper white! It is a wizardly example of paper folding -- and will appeal more to older children because of the engineering.
I did not get a response from the grandchildren about this one -- it sort of got lost in the holidays. Maybe next year they will discover it and enjoy it.
