I tend to be quite a stingy rater ... a book will only get 5* if it truly blows me away and I would read it again.
1* means I really didn't enjoy this book, and probably didn't finish it. If I did finish it, it was a struggle.
2* means the book kept me engaged enough to finish it but I didn't enjoy it and probably wouldn't read anything else by this autho
3* - this is a good book! It kept me interested, and I would consider reading more by this author.
4* - a great read! I was immersed in the story and would recommend this book!
5* are saved for absolute "wow" books. This doesn't happen very often.
