Well, it didn't take me very long to finish The Unwritten Rule because it is a quick read, and, by the middle of the book, I just wanted to get it over with. In a nutshell, Sarah liked Ryan. Ryan liked Sarah. Ryan got with Sarah's best friend Brianna instead. Enter Love Triangle. This book just gave me about two hours of frustration. One word: Forced. Everything that happened, decisions the characters made, and the characters themselves seemed forced. No one owned up to anything until the end of the book, which was obviously done to make the story longer, and it left a bad taste in my mouth. I've read a couple books many years ago featuring a love triangle and I remember enjoying them, because I rooted for the characters and I rooted for the couples. Most stories centered on love triangles, with the exception of the couple I've read before, are not executed very well. The characters involved just make one bad decision after another, the characters and couples lose their likability, and it just turns into a big old mess. I found myself unable to feel any sympathy for Ryan, Brianna, or Sarah, because I was not given the chance to know them. Right from the start, the love triangle has already begun without first establishing the characters. If I'm going to read about a love triangle, I want to know and love the characters, see both couples together, be able to root for them, and enjoy their overall journey, which I was not able to do with The Unwritten Rule. 
 Side note: Brianna makes me sick. The subtle jabs she always flung at Sarah, her supposed best friend, and just her overall attitude made her really unlikable. Referring back to FORCED, it seems Brianna's character was butchered on purpose just to try to make readers root for Sarah and Sarah and Ryan, which also left a bad taste in my mouth. I don't like when authors try to tear down characters just to make other characters look better, and that's the vibe I was getting with Brianna throughout the entire book.
