Did the synopsis make your heart race a tiny bit? Because my heart did! As soon as I received Premeditated, I picked it up immediately. I love mystery/thriller plot lines and this one screamed just that. Dina, the main protagonist, is out to get revenge on the person who caused her cousin Claire to cut her wrists. She enrolls in his school, and starts formulating a plan to turn his life into misery, which is still a small price for what he has done to her family. 
 Immediately, I felt that I couldn't connect with Dina. From the way she never stood up to her tyrant of a mother to the way she was able to so easily justify everything that she wanted to do. But my main reason was my suspicion towards a character in the book that she was friends with. I am not saying anything else so as not to give anything away. There are some characters I really disliked in this novel (mostly from her new school) but I really liked her two friends, or should I say partners in crime. I do believe the author tried too hard in creating their 'teenage rebel' image but I didn't care since I loved both of their personalities. The acts of revenge in the book are spread throughout. There isn't a build up to this huge revenge plan that only gets executed towards the end. However Dina performs little operations here and there that cripple a different piece of his life every time. I found that to be smart, and easier to digest. I am not a fan of big buildups so this was perfect. 
 The target of Dina's revenge is Brooks, and I immediately had mixed feelings about him. He seemed sweet but you can't help and remember what happened with Claire, especially if he is a trust fund kid.. we are told not to trust them since they seem to get away with anything. This book isn't big on character development except for the main protagonist, but the author knows how to keep you wanting more and asking questions. While the plot is mainly about the revenge, you do follow Dina's arc of development, especially with the revelation of a twist towards the end of the book (I already guessed what it was halfway through). To put it simply, if you are a fan of thriller/mystery novels, then I suggest you pick up Premeditated. I personally could not put it down and ended up reading it in less than two days.
