g married for the second time, but that doesn't mean she can't go all out for her bachelorette weekend. She's booked three days of super-exclusive luxury accommodation on a remote Scottish island for herself and six other women. There's Jen's tennis coach and a fellow tennis-playing fashionista; a famous pop star and that pop star's estranged ex-bandmate; plus Jen's future sister-in-law and the sister of her first husband.

The helicopter won't be back for seventy-hours and they have the island all to themselves--or so they think. As the cocktails flow, old grudges begin to emerge and tempers to fray. Then one of the women goes missing. The others receive a threatening message urging one of them to confess a terrible secret. But whose secret is it? Each woman has a darkness in her past she's reluctant to admit. But they'll all have to come clean if they want to make it off the island alive.
