Question: This book was interesting with great promise. The premise was fascinating but the writer fought with herself throughout. She spent a great deal of time on the flora and the fauna. There was always a paragraph on a bush when a sentence would do, a sentence on a tree when a word would suffice. The characters were well developed. Over all it was a good read.

Answer: Negative

Question: This book isn't worth the paper it is written on!!It contained nothing of substance.Where did this couple live?What were their last names?What was a day like at home for the mother(Hyacynth)?What were her children like?What was important to her?These are just a few of the subjects not even touched upon by the author.I couldn't get past the first 100 pages.I hav not read any of this authors other books since Evergreen,which I loved.This book was a waste of my time and money.I will not ever waste anymore money on this authors books.

Negative
