A Complete Guide to Reese Witherspoon's Hello Sunshine Book Club Picks

"The Marriage Portrait" by Maggie O'Farrell ($17)

• What it's about: "The Marriage Portrait" follows Lucrezia, the third daughter of a Florentine grand duke. She's content with her quiet life — until her older sister dies, forcing her to marry into royalty and thrusting her into a spotlight she never wanted.
• What Witherspoon says: "I could not stop Googling all the details of this true story. It's a fascinating, historical thriller about an Italian Duchess, who we learn at the very beginning of the book will die either by sickness . . . or by her husband's hand. I can't wait to hear what you think!"
