5 stars: I can't stop thinking about this book. I likely stayed up all night to read it. I was wowed by the originality, characters, plot, or development. I would recommend this book to everyone. I will buy from this author in the future.
4 stars: The book ad no problem passing the set down/pick up test. I love almost all of the plot and characters and thought any flaws were negligible. I would recommend to almost anyone.
3 stars: A completely average read. Some good things and some bad things. I might recommend it to a friend depending on what exactly their tastes are, but it probably won't stick with me personally in the long run.
2 stars: The book struggled (or failed) to pass the set down/pick up test. There were major flaws and/or plots that annoyed me. I would not recommend it to anyone.
1 stars: I can't stop thinking about this book. I likely threw it at a wall or trash can. I was wowed by stupidity, typos, lack of character development, bad dialog, or simply the fact it was published at all. I will avoid this author in the future.
