Does anyone here have an idea of an age range for readers of the book? I have several young relatives who I think would enjoy the story but not sure which of the four I should purchase this for. I know kids can grow into books, but if you get something for Christmas you don't want to be told in two years you'll enjoy this. Ages: 5 (too young I think); 7 (maybe young, but also loves all things creative); 9 (I may have a hard time getting the book away from his Mom because she will love it) and 10 (appropriate but he has dyslexia - if it is too verbose he may tune out). Any advice or thoughts would be appreciated.
