Something borrowed

Something Borrowed tells the story of Rachel, a young attorney living and working in Manhattan. Rachel has always been the consummate good girl---until her thirtieth birthday, when her best friend, Darcy, throws her a party. That night, after too many drinks, Rachel ends up in bed with Darcy's fiancé. Although she wakes up determined to put the one-night fling behind her, Rachel is horrified to discover that she has genuine feelings for the one guy she should run from.--From publisher description.
