I found this to be an excellent book to help increase my daughter's vocabulary as well as help with literature. She is an avid reader (to the point of obsession) but I didn't think that she was getting a clear picture of what she was reading from a literary point of view. This book is divided into 12 short lessons that have practice sections that include how they are used in a sentence, vocabulary and more. The book allows her to work independently and the words get more difficult as she progresses. Great Book!!!
