Madison lives with her father and eight brothers. Her mother died while giving birth to Madison even though Madison is a twin, her brother was still born before her. But Madison has a secret that not even her family knows about, she's a street racer. She doesn't say a word to anyone, just grabs the money for her family, and goes. Police have tried to catch her, and failed, and even some of the guys she races with have tried to find out who she really is. But no one has gotten close enough to even know that she's a girl, everyone thinks she's a guy, MM, or Mystery Man. She's been street racing for a year and has had no problems with anyone. So when a bad racing gang comes to town they are looking to see if MM is good enough to join. The gang is run by the father's son, the one who will be taking charge of the gang soon, and he's only eighteen? What will become of Madison when her street racing life just got to a whole new level? (There might be a lot of cursing in this story, you have been warned)
