Revenge is a dish best served cold. Boys are just familiar with it. Girls know it. And that's why they do it better. Three girls, three stories, three revenge plans. One goal. Make the people who tortured and hurt them pay.
And in the end we have Mary. A girl who had such a traumatic experience that she decided to leave her school and her old life behind and move forward. But in order to do so, she must face her demons or maybe one demon in particular. And he's a quite easy demon to find. The only thing she has to do is enroll in high school and just her luck; he's one of the first people to see. And the one who will pay for what he's done. Moreover Mary, apart from being a heart-broken and traumatized girl, she may have a secret talent she isn't even aware of. That's what the course of events leads us to believe throughout the book.
Burn for burn, the first book in the Burn for Burn series is not a story of forgiveness. Who cares about forgiveness when revenge is so much more fun?
