Input:
I'll admit to judging a book by its cover, almost not opening this one up. Linda Nichols developed a great plot, bringing her characters to life with picturesque descriptions and background information that allows the reader to understand why these people ended up in the life they found themselves buried in.

Nichols not only allows us to understand the background, she took us into the struggles and the thoughts of her main characters. A very well-written book that I didn't want to put down until it ended.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: A: very positive
