The plus one : a novel / S.C. Lalli.

The wedding of influencer Radhika Singh and hotel developer Raj Joshi, a week-long affair at a luxury resort in Cabos, won't just be the event of the season--it will also mark the union of two powerful and wealthy Indian-American families. Everyone who matters will be there. The outfits will be couture. World-renowned chefs and decorators will be flown in. No expense will be spared for what Radhika and Raj have coined "R&R," a week of rest, relaxation and celebration of their love. Shaylee "Shay" Kapoor is an outsider with an agenda of her own, but she just so happens to be dating Raj's best friend, Caleb Prescott III, and is the unwelcome plus one at the wedding. Then, on the day before the ceremony, Raj and Radhika are found dead in their luxury villa, both with gunshots to the head. Chaos descends on the hotel. Shay, the apparently devoted girlfriend, stays by Caleb's side as the investigation unfolds, while family and close friends grieve and accusations run wild. The police believe the murders are a drug cartel hit, but the doors to the couple's villa have state-of-the-art locks. There was no way for the murderer to slip in. The only ones who had a key were the bride's sister, the best men and the wedding coordinator. Shay may be an outsider--and she definitely has secrets of her own--but she seems to be the only person with enough perspective to untangle everyone's lies and discover why anyone would want the bride and groom dead.
