I felt this book was well written and would be a good story for anyone under the age of 10. I am 11 years old and I felt that Pip was really annoying. She acted much younger than the 11 year olds that I know. It would have been better if Pip was more around the age of 8 or so.
I really enjoyed the second part of the book though. Reading about the same experiences but getting an understanding about how the horse perceived the moment was really cool! The author obviously knows a lot about horses and how they behave.
