This is what Amazon wrote about A Promise of Passion.
They say you never forget your first kiss, your first touch—your first time making love. Katie knows she never will.
A Promise of Passion follows the love affair of Katie Donovan and Bryce Collins, a budding high school romance destined to last a lifetime. Throughout the challenges of college, a long-distance relationship, and the rigors of careers, their flame only burns brighter. To Katie, Bryce will always be her "walking Adonis." And for his part, Bryce has been enthralled by Katie since their high school physics class. Theirs is the storybook romance that everyone dreams of.
But if that's the case, where's Bryce now? Katie struggles with this question as she sits alone in a bar drinking a gin and tonic with an olive—their favorite drink. They always kept their promise, a vow to keep passion alive no matter what. Why would he break it now?
