Heart the Lover by Lily King

Our narrator understands good love stories - their secrets, their highs and free falls. But her greatest love story, the one she lived, never followed the rules. \n \nShe was in her senior year of college when star students Sam and Yash swept her into an intoxicating world of academic fervour, rapid-fire banter and raucous card games. Their lives became quickly intertwined - with friendship but also with unpredictable passions and the intimations of first love. \n \nDecades later, she is a successful writer, living a comfortable life with her husband and children, when a surprise visit brings the past crashing into the present, forcing her to confront the decisions and deceptions of her youth.
