Runaway

Caitlin Tanner didn't have a normal life from the beginning. With criminal parents who wanted her to be the same way, she was doomed from the start. Her only hope were her three brothers. When she turned 10, her older brother Bigby had enough. He wanted to protect her from their parents, so he told her to run. Run and never look back. And that's exactly what she did. Now, she's 17 and has been on the run for 7 years. She's been successfully hiding from her parents all these years, but she also hasn't seen any of her brothers. Caitlin is lonely, and doesn't know how much more she can take of the "trust no one" road life. That's when she meets the Diaz brothers.

At first she is adamant that she can't trust them, but nonetheless, the brothers still get under that hard shell of this runaway. When Caitlin helps them out Sean offers her a deal that she can't refuse. But, shit is gonna get complicated fast. But, a Tanner never backs out of a deal. This was no different.
