Susan Fenn has loved Ethan Roth for ten years. She thought the man who had protected her since childhood would be her lifelong partner. Until he stood with another woman and publicly announced their engagement. Everyone expected her to break down and cry, but she was surprisingly calm, packed her belongings, submitted her application for a cutting-edge scientific research project, and resolved to completely walk out of his life. Only after she vanished entirely did Ethan Roth come to his senses. The girl who once only had eyes for him would no longer wait for him in place. This time, he is the one rushing, desperate to win her back.
