Strained Relations: 6 Horrible Sisters in Fiction

This list of fiction books about evil sisters is sponsored by The Summer of Sunshine & Margot by Susan Mallery.

Twin sisters Sunshine and Margot are as different as chalk and cheese, but what they do have in common is a complete lack of luck when it comes to love. Emotionally stunted by a mother who dropped everything to follow boyfriend after boyfriend, the sisters have ever only had each other for support and to share a pint of post-heartache ice cream. When Margot, an etiquette specialist, is hired to work with Bianca, an icon from Hollywood’s Golden Age with romantic entanglements of her own, she and Sunshine become the daughters she never had, and their friendship teaches them how to embrace the quirks that make them unique, and how to demand the love they deserve just as they are.


I am always fascinated by sister relationships in television and books, because I don’t have a sister. (I did, but I ate her in the womb like a baby shark.) I wonder what it would be like to have had a sister. Would we have gotten along? Would we have been enemies? Would I have been—gasp—the bad one?? (SPOILER: No doubt.)

But there’s a difference between sisters who fight over things like whose turn it is to do the dishes and the sisters in this list. These sisters are BAD. And that’s what makes them so much fun. Let us know your favorite evil sisters in the comments!
