The wedding of Radhika Singh and Raj Joshi, a weeklong affair at a luxury resort in Cabos, isn’t just going to be the event of the season—it will also mark the union of two highly influential and wealthy Indian-American families. No expense will be spared. Shaylee “Shay” Kapoor is just an outsider, but she just so happens to be dating Raj’s best friend, Caleb Prescott III. But on the morning the wedding festivities are supposed to begin, the resort’s wedding coordinator Daniela makes a frightening discovery: Raj and Radhika are dead, gunshots to the head. Chaos descends on the hotel as the guests are turned away or sent home. The police believe the murders are a drug cartel hit. But there was no way for the murderer to slip into the room without a key. And only the sister of the bride, Zara; the best men, Caleb and Sean; and the wedding coordinator, Daniela, have keys.
