Example Input: I was disappointed in how the book ended. She could have expanded more on the storyline of Celine dealing with her cancer and her relationship ending with her husband. It's not one of her better published works.
Example Output: 3

Example Input: Great case and looks fantastic! A part of the rubber on the bottom of the case was snapped in half when it came out of the package. Other than that it is a fantastic case!
Example Output: 3

Example Input: I bought 2 of these one for me and another for my hubby. Got in red and blue. Color and cover are as described. However, it gets only 3 star for the very cheaply made screen protector which keeps getting finger smudges and not very sensitive to touch. It doesn't even feel like tempered glass but looks and feels more like plastic made. I would invest in separate glass protector. My husband had to remove his to make the touch screen work! Would rather some few more bucks and get a better one.
Example Output:
