Viper's Run(Last Riders‪)‬

Winter Simmons received the surprise of her life when she discovered that the man she had been dating for the last two years was actually Viper, president of The Last Riders. A high school principal, Winter has no intention of ruining her reputation in the community to be with a man who betrayed her trust. Unforgiving, she turns her back on him.
Determined to find his brother's killer, Loker James kept his identity as president of The Last Riders a secret from Winter. When the truth comes out, he is determined to make her see the real man who can control not only a group of dangerous bikers but a woman whose life is a rulebook. Unable to prevent herself from being drawn into the very club she despises, Winter is about to lose everything that is important to her-unless Viper can prove that she's more than a moonlight run.
