Margaret Drabble and A.S. ByattRead about the other entries on the list.
Sisters Drabble (The Pure Gold Baby) and Byatt (Possession) have between them won dozens of awards, sold a mess of books, and earned literary reputations many would kill for. They also, in no uncertain terms, hate each other. They throw shade at one another in both interviews and in their fiction, and haven’t spoken in decades except through withering insults offered up in interviews. Neither ever fails to say something negative—sometimes openly hostile —when the other publishes a new book. The product of an intensely unhappy and ultra-competitive upbringing, each remembers the other being mother’s favorite, and resents it with a passion. It’s entirely possible that, had the sisters evolved different artistic interests, they’d have maintained a relationship. With both of them pursuing storied literary careers, however, their sibling rivalry was doomed to blossom into something that can be culled only with fire and blood.
