I like The Unwritten Rule. 
 ***** 
 I know who I want to be with, and it isn't her. 
 I liked how the story started out, but halfway through I was getting riled up over Sarah and her constant inner turmoil. It has a good premise, considering the cliche of the plot, but the abrupt ending irked the little patience left in me. 
 Sarah and Ryan had a (kind of) history. And i really liked this part because it goes to show that Sarah didn't just like Ryan on-the-spot, when he started going out with Brianna. It further validates Sarah's feelings as something built on easy conversations, silent touches, and delicate friendship. Ryan is adorable, what with the tension with Sarah while being with Brianna. I wished he had the guts enough to break it off with Brianna earlier when he felt his strong feelings with Sarah. Still, Ryan is a very, very sought-after-worthy guy. Brianna is a best-friend-cum-mean-girl and that makes her dangerous. If it weren't for Sarah's mom pointing that out indirectly, I wouldn't have noticed. But yes, she's toxic in a subtle kind of way. 
 Those heart-thumping scenes with Ryan and Sarah are memorable and suspenseful. If it wasn't for these moments, I would've slammed this book outright. Not because the rush it give, but for the conflict it gave to both Ryan and Sarah. Ooh, it is wrong, you bet they know it, but (just like Sarah said) STILL, I WANT. 
 To date, this by far has the most sucky ending i've read in a contemporary setting. I was just left hanging... without tying up all loose ends. Ugh.
