Feel the Rush

When there's nothing but old friends tying you somewhere, it's pretty easy to leave. That's what Sienna did, she had nothing left tying her to her hometown except an old gang, her Uncle and a few friends. She leaves, looking to just be on her own for a while but that's before she meets Kieran and his friends. They run a gang and are looking for someone with the skills Sienna has. Sienna agrees, loving the rush she gets but who is this Boss person currently locked up and what kind of trouble will Sienna be brought into with these boys?
