Sarah Thompson was stunningly beautiful, compassionate, and unblemished. The only thing she wasn't was eighteen. Her talent was writing, her nemesis-math. Enter Travis Hall-highly disciplined and accustomed to getting what he wanted. A master at math, Travis comes to teach at Sarah's high school in 1962 after suffering a life altering event. His plan hadn't anticipated Sarah, whose aqua blue eyes seduce him, but whose open heart teaches him how to love. During tutoring sessions their mutual attraction grows into admiration overcoming their opposite natures. Passions simmer while their forbidden love is left unspoken taking each of them on a journey of the heart. As the year ends, Sarah remains off limits, the only prize he can't claim-though that doesn't mean that he can let her go. The Equation chronicles a compelling tale of unrequited love that spans decades, from Long Island, New York, to the great American Southwest. This epic story stirs the heart in all of us who have looked back across the bridge of time to touch the hand of the one we never forgot and always loved.
