When Sally Hepworth’s “The Good Sister” was released in April, it became an instant New York Times bestseller. Available now in paperback, this suspenseful thriller about twin sisters Fern and Rose is summer escape at its finest (be warned, you may chew your nails.) Sally spoke with Olivia about crafting the dual narratives, how organically the character of Fern came to the story, the part of her writing process that is like “a dagger to the heart” for other writers, and self-expression through fashion. “The Good Sister” is published by St. Martin’s Press.

In A Moment with Margaret, Margaret shares which thrillers she’ll be reading this summer from authors she’s enjoyed in the past: “The Maidens” by Alex Michaelides, “Survive the Night” by Riley Sager, and “The Perfect Family” by Robyn Harding.  These books are released in June, July, and August, respectively.
