Harmless is one of the best books I've read in awhile. The plot of this book is intriguing and its characters are super realistic. The basic gist of this story is that three freshman girls, who're pretty average nice girls, get caught in a lie by their parents. Rather than suffering the punishment for their lie, they tell a HUGE lie to make their parents feel bad for them. After this, the lies start to spiral out of control and end up impacting their entire community.
This story is narrated by the three girls and it goes back and forth between their distinctly different voices. It is an interesting read and you'll definitely want to figure out what happens in the end. This would be a great book for discussion, so maybe you can invite a friend to read it when it's done and have a mini book group session.
