Yes, there was plenty of revenge seeking and back stabbing. There was also a fair amount of cheeky comments and sass. But the unexpected surprise hiding on these pages is the paranormal/supernatural element with one of the characters. Now, if you're one to avoid books that might lean toward the supernatural, do not fret. It is such a small detail in this book that you might even miss it.
One of the things I found the most interesting about this book was the characters. The three girls that tell their stories in alternating voice/chapters had very differing reasons for seeking revenge. I was worried it would be choppy with that many narrators, but I think the authors pulled it off well. They were able to make each girl's voice unique in the book. I also liked how the three girls (Lillia, Kat, and Mary) were so very different from one another. That really brought an interesting element to this group of revenge seekers.
For the most part this was a contemporary read. It takes place in a high school with typical and expected high school drama. There are some underlying subplots that are important, but don't take center stage in Burn for Burn. I expect they will get more face time in the next book, Fire with Fire.
So, overall, if you want a quick read that appeases your inner scorned teenage self, you'll probably enjoy this one.
