I do not think that the age group indicated is at all accurate. The edition (Wordsworth Classics) is advertised as being for the age group 8-12, but after purchasing the book I noticed that it is the complete and unabridged version. Not at all suitable for my 11 year old son who is an average to good reader. In deed, my 14 year old son found this book to be more appropriate for his age group. Very disappointing.
