The Housemaid

Not anything special or amazing, but for commercial fiction, it was pretty great. It gave me what I wanted, fulfilled all the obligatory beats for a book of it's kind:
1. air-headed protagonist who is dumb and air-headed to make the mystery stuff last longer
2. romance, affair, yadda-yadda drama
3. suspense with fast pacing
4. fairly likeable protagonist
5. unexpected yet justifiable plot twist
The plot twist was well done because it was completely unexpected despite its being set up in prior chapters right under the reader's nose. It wasn't like the twist revealed some secret of the human nature to me or anything, nor did it have any deeper meaning under “cool plot twist”, but it was satisfying and, well, gave me that pleasant jolt of surprise that every commercial fiction plot twist should. I consider this a great book because it's the kind of story I can recommend to anyone. I could recommend this to my boss, my mom, my friends, my coworker. I think a really good book appeals to everyone, and this book certainly appeals to a general audience. It's also original enough, and it lives up to the expectations it sets for itself. Because of this, I think it deserves 4.8 stars.

Nothing literary by any means, but good entertainment.
