First part of a serial. Rosalie is determined to create machines, making them work. Her father allows her to tinker but rather she wouldn't. He hires Edmund to care for her while he is away. Edmund does that until the unexpected happens, blowing apart Rosalie's room and world. Edmund and Rosalie give into their feelings and they promise to get revenge together. I loved Rosalie's determination to do what pleases her, not what others expect. Edmund supports her to the end.
