Marguerite Gray is a lifestyle icon known for her garden parties, high-end business ventures, and being the muse behind the famous Serge Kuhnert painting, Marguerite by the Lake. For the last few years, Phoenix has been the gardener on the famed Rosecliff grounds, home of the Gray family: Marguerite and her husband, Geoffrey. When a storm threatens the launch party for Marguerite’s latest book, it’s Phoenix who spots the danger to the guests and rushes to Geoffrey’s side to save him from a falling tree. She senses the danger of being drawn deeper into their lives, but she becomes embroiled in an affair that could destroy her career. But soon after the affair begins, Marguerite falls to her death, from the same high point at Rosecliff where she posed for Marguerite by the Lake. Now Phoenix has another secret, one that haunts her even as Geoffrey invites her to move into the manor with him.

As a photographer, Delta Dawn observes the seemingly perfect lives of New York City’s elite: snapping photos of their children’s birthday parties, transforming images of stiff hugs and tearstained faces into visions of pure joy, and creating moments these parents long for. But when Delta is hired for Natalie Straub’s 11th birthday, she finds herself wishing she wasn’t behind the lens but a part of the scene --- in the Straub family’s gorgeous home and elegant life. That’s when Delta puts her plan in place, by babysitting for Natalie; befriending her mother, Amelia; finding chances to listen to her father, Fritz. Soon she’s bathing in the master bathtub and eyeing the beautifully finished garden apartment in their townhouse. It seems she can never get close enough, until she discovers that photos aren’t all she can manipulate.
