Heart the Lover (original) Lily King

She 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.

Decades 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.
