Elise meets Donald on a flight to Washington, D.C., where he teaches and she edits self-help books. He is dreamy: 6'6'� with unflinching green eyes and a proclivity for speaking frankly. Incredibly, they fall in love, get engaged, and start discussing wedding invitations.

And then Elise meets her - Adrienne - Donald's stunning, leggy ex-fianc�e. Adrienne is newly single and planning a move to D.C. Cleavage-baring, half-French, and with a degree from Yale, she seduces men with one flick of her hair. Worst of all, she and Donald have remained 'good friends'� since they broke up. Convinced that Adrienne is out to win Donald back, Elise begins stalking both of them obsessively . . . and starts adding up clues to what looks like a brazen affair.
