Fool Me Once…Shame On You
Fool Me Twice…Shame On Me
Fool Me Thrice…Shame On Both of Us

For three years, Gordon was Kayla’s best friend and trusted confidant. Their only communication was online, but she felt safe sharing her deepest, darkest secrets with the man who had deeper and darker secrets of his own. But six months ago, everything changed. Kayla changed, and Gordon had no place in her new life. After seventeen years of being an outcast, Kayla started making friends, dating, getting involved with school activities—being a normal teenage girl.
Now Gordon has decided he wants Kayla back and won’t take no for an answer. She can cry, and beg, and try to push him away, but he is never letting her go. Being with Gordon will cost her everything, leaving no room for her family, her friends, or the future she was on track to achieve. But he could also be her one chance at a life that feels good instead of one that just looks good.
Gordon is used to breaking the rules and stopping at nothing to get what he wants, but Kayla has to decide whether she can throw that much caution to the wind for the sake of true love.
