When her first novel, “The Miniaturist,” was released two years ago, author Jessie Burton wasn’t prepared for the attention and pressure that writing an international bestseller would bring. In her latest novel, “The Muse,” she explores how we struggle with ambition, identity and desire through the fictional stories of two women—one in 1960s London, the other 30 years earlier on the edge of the Spanish Revolution—and how their lives intersect in a single mysterious painting. Author Jessie Burton talks with Diane about her latest novel, the dark sides of success and what it means to be a muse.
