Needing to pass her Math class after years of attempts, Alexa coaxes her sister into taking the exam for her. All she has to do is fill in as the assistant for Alyssa’s jerk boss. It should be easy since they’re twins, but Alexa’s nothing like her sister in personality. The second they meet their attraction is hard to ignore. Alexa knows that she can’t keep the secret for long because Mr. King does something to her mind and body that no one else has. Can she fool Mr. King into believing she’s Alyssa, or will he catch on to their little ruse?
