This is book 4.5 in the Beat and the Pulse series. You don't need to read the other before reading this. It is a quick, fast read.
We actually meet two new characters in this book, Rebel and Charlotte (or Charlie).
Rebel is in the run for The Undergrounds championship. He is only doing it for this season, he needs the money so that he can make something with his life. He's been in trouble before, grew up in foster homes. He is cocky and I loved it!
Charlotte is a detective. She's young, but her career has kind of stalled. She gets the idea of her taking The Underground down. But then she meets Rebel and things go off like fireworks.
I love both of these characters and their story. I want more from them!!
