A self-made billionaire, his high school sweetheart, and the horrible truth that threatens to keep them apart. On the night of their high school graduation, Grayson Matthews asked his girlfriend's father if he could marry her. He wasn't expecting excitement-them being so young-but the blatant refusal and threat to disown Emma if Grayson ever said a word came as a complete shock. Knowing he couldn't stay in town and watch her fall in love and marry someone else, Grayson left. Now, ten years later he's back, and with that secret still hanging between them, his only choice is to keep her at a distance so the truth never hurts her. Emma Lane still can't understand why her high school sweetheart left without a word. They'd talked about getting married right after graduation. Her whole family loved him, including her dad. Now Grayson's returned and tight-lipped about why he left. She wants to hate him, but her curiosity-and some meddling by her sister-launches her on a mission to uncover the truth. She'll get answers, even if it means getting close to someone who might up and leave her heartbroken again.
