Something Borrowed/Something Blue (abridged)

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 30th 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.

Darcy Rhone thought she had it all figured out: the more beautiful the girl, the more charmed her life. Never mind substance. Never mind playing by the rules. Never mind karma. But Darcy's neat, perfect world turns upside down when her best friend, Rachel, the plain-Jane "good girl," steals her fiancé, while Darcy finds herself completely alone for the first time in her life…with a baby on the way. Darcy tries to recover, fleeing to her childhood friend living in London and resorting to her tried-and-true methods for getting what she wants.
