Karissa Ruining Life at its Finest for Montana?

As if Montana's life wasn't hard enough, now her dad was getting to involved. We find out throughout the book that Montana's dad always seemed to have a new girl around. We never caught an eye of his taste, but then we find out when Montana goes to dinner to meet her new possible step mom, she sees it is Karissa, her "best friend". This made her feel insane. How could this be happening? As I got deeper into the book, it reminded me very much of the book "The Secret Year" by Jennifer R. Hubbard. Although they do have their differences, it still reminded me of it. Just like in this book, in The Secret Year, Julia(main character) faces many family problems along with social problems at school. She was a rich girl who got everything she asked of, but this was not the life she wanted. She got caught up trying to find herself in the midst of it all and it ended up leading to bad friendships and relationships just like Montana faces in "Making Pretty." Montana thought that everything was going to turn out good, she was having such a fun summer with Karissa. This was, until one day when she goes to meet dad's new girlfriend, there she was! This was crazy, all the illegal things she has been doing with Karissa. Was her dad going to find this out, or did he even already know? Although, Karissa does not see a problem with her and Montana remaining best friends, I could understand where Montana is coming from.

Karissa says to Montana "What if this was really good for both of us?"
In the book Montana describes the way she feels as "I hate her and love her. I want to yell at her about finding her own family, not stealing mine. That dating my dad is disgusting. That she's a liar and a fake and an awful person who I wish I'd never met."
Then again, she is worried about her. She knows her dad is going to hurt her, and she knows everything about this girl, it was her best friend! At this point of the book, Montana just feels so lost with herself and doesn't know what to do anymore. 

Everything was fun and games, until now when Montana is left feeling more alone and depressed than ever. She feels back stabbed, just like in "The Secret Year" Julia also feels a bit betrayed after what happened. Have you ever felt betrayed by someone you thought was your best friend? If so, how did it make you feel? I know I personally have been and it was not a good feeling. No feeling of betrayal would ever feel good, and that is what these two authors are trying to show in the books. These girls are going through a rough life. Being a teenager is difficult as we face the stress of high school, friends, family, and finding ourselves along the way of it all. 

Along with all of this happening in Montana's life, there is still this boy from the park. Eventually this boy works up the courage to go over and talk to her at the park. Throughout the book, they start getting to know each other more and find out they actually have a lot in common. Montana finds a heady distraction in Bernardo. He’s serious and spontaneous, and he looks at Montana in the way she wants to be seen. For the first time, Montana understands how you can become both lost and found in somebody else. But when that love becomes everything, where does it leave the rest of her imperfect life?
