The only way the system was reliable when it came to Tiffany Dempsey was in failing her. Once again, it'd done just that, but this time, she wasn't about to accept that nothing could be done. This time, she went to a source outside the law for help. She's gone to the Sacred Hearts MC, a club whose reputation for bloodshed and violence precedes them. It's a gamble she's willing to take; desperate times call for desperate measures and she's never been more desperate than she is right now.
Zeb joined the Sacred Hearts by way of a second chance when he thought he had none. He's determined to do right by his club and himself by changing his ways. So, when Dragon, his president, asks him for help, he doesn't hesitate. He's more than happy to give the pretty little stripper with the scarred up face a second chance of her own. The way he sees it, a survivor like her has more than earned it.
Neither Tiff nor Zeb expected that this protective detail would be anything other than a strictly business-like arrangement, but the two find quickly that they complement each other in just about every way. Maybe, just maybe, it's what Dragon had planned. After all, the president of the SHMC is sort of crafty like that.
