A perfect marriage dies in paradise.
Sienna Langley was a workaday marriage therapist. Then her bestselling book made her a star. Now she and devoted hubby Colby are the internet's favorite couple to love and relentlessly scrutinize.
Staying in a glamorous Bali villa for their anniversary should be a joyous time. But Sienna feels something bad coming on. There's a new letter from her stalker, "Number One Fan." There's Cassidy, the young female butler assigned to them, whose attentions seem unnervingly personal. And Colby keeps planning romantic excursions that Sienna can't bring herself to attend.
When tragedy strikes in paradise, whispers ripple through the resort: Was it an accident ... or something far more sinister? As suspicion swirls and secrets surface, it becomes clear that nothing about this trip--or this marriage--is what it seems.
