An unhealthy friendship takes a sinister turn. Almost everyone has a friend whom they barely tolerate. It's that person whose jokes are always annoying, who tries to butt in on nights out, or who keeps coming over unannounced. For Martha, that friend is her new neighbor, Jennie.

Jennie worships Martha. She loves everything about her: Martha's house, Martha's impressive children, Martha's attractive husband, even the way Martha dresses. But when Jennie starts changing, gaining confidence and succeeding in love and work, Martha's life begins to come apart at the seams.

Gillian White's Copycat is a biting suburban satire about a fraught relationship between frenemies taken to its most extreme conclusion.
