Tess is the bad girl. The one everyone "knows" is easy and only worth a good time. Lucas is an ex-con. They are both bad news, awful people, right? Wrong! They made mistakes. They are guilty of some unsavory behavior. What they are not is a lost cause. Lucas treats Tess like a princess. There have been squeaky clean heroes in other novels that have not respected their heroine as much as Lucas does Tess. The true test of their love is that they make each other better people. I can easily see Tess and Lucas going the distance. They make each other happy, they are in love, they are their best selves together. That makes for a pure and perfect love.
