Nicky Wilson tells other people's stories. A successful ghostwriter, she's penned tell-alls by actors, athletes, television chefs--weaving interviews and anecdotes into memoirs of love, loss, and overcoming adversity. The celebrities get bestseller status, while Nicky pockets her paycheck and moves on.

Olivia Hayes, Nicky's new client, is the Martha Stewart of influencers, a domestic goddess with a perfectly accessorized home in the English countryside, a handsome husband, and impeccable taste. Through thousands of artfully hash-tagged posts, Olivia shares endlessly, while somehow retaining an air of mystery that enthralls her followers.

Olivia agrees to let Nicky into her house for a week, though she's frustratingly aloof at first, and seems resentful of Nicky's presence. Yet little by little, Nicky breaks through the cracks in the glamorous fa ade. She notices Olivia's strained relationship with her husband . . . her overcautious parenting of their toddler . . . the money worries the family can't hide. And then there are deeper secrets--including a tragedy that may shine light not just on Olivia's past, but on how far she'll go to preserve the life she's made.

Soon, Nicky will learn the truth about Olivia. But it may be much more than she wanted to know . . .
