⭐️ – It was awful.
⭐️⭐️ – It was okay. I don’t have many things I love about this book, but it wasn’t awful.
⭐️⭐️⭐️ – It was good. It was worth reading, but there may be things I really didn’t like mixed in with things I really did. Could be considerably better, but I don’t feel it was a waste of time to read.
⭐️⭐️⭐️⭐️ — It was great. There are some things that could’ve made the book more enjoyable, but overall it was a positive experience.
⭐️⭐️⭐️⭐️⭐️ – I loved it. This book will leave me thinking about it. It may still have issues, but to me, a 5-star book is one that I loved and will leave a lasting impression on me.
Obviously, with context, different factors are going to go into each book rating. But this is the general idea I follow when choosing how many stars to give a book.
