What should you do if a baby falls through your window in the middle of the night? There's no subreddit forum for that question. Florence and Grace have been bitter enemies towards each other since elementary school. Florence's dream boy fell into Grace's arms in the 6th grade which resulted in years of torment and bullying for Grace that she has grown to resent Florence for. None could forgive the other for what they did back in their adolescent years and have since avoided each other for the majority of their time in high school. And to top it all off, they were next-door neighbors. But what happens when they both experience the same life-changing event one late night? A boom sounds, inaudible to the rest of the world but them, and what remains is a baby that has just flown through Grace's window. In this science fantasy young adult novel, these girls slowly start to understand their differences and forgive each other's wrongdoings as they attempt to solve the mystery of the baby that has just fallen from the sky.
