Some weddings end in forever. This one ends in murder. Wedding planner Elena Reyes has spent eight years making other people's most important moments perfect. She has never lost a groom before. When Singapore's most high-profile groom drops dead at his own rehearsal dinner — poisoned in front of ninety-three guests at a cliffside Sentosa resort — Elena is left holding the evidence, the guest list, and the dangerous attention of whoever arranged it. Her only ally is Marcus Vale: the brooding, grey-eyed ex-Interpol agent who was the best man, is now the prime suspect, and has spent three years hunting the criminal syndicate that destroyed his career. They shouldn't trust each other. They don't have the luxury of alternatives. As the investigation pulls them deeper into Singapore's glittering underworld — shell companies disguised as wedding accounts, a network of power called The Veil, and a killer still working the room — Elena and Marcus discover that the line between protection and possession blurs very quickly when your lives are on the line. Marcus doesn't do gentle. He is relentless, commanding, and utterly certain — and when Elena is in his arms, she forgets why she ever tried to manage her feelings from a professional distance. But the man claiming her body every night may be carrying secrets that could cost them everything. In a city where weddings hide murders and trust is the most dangerous currency, Elena must decide if she can hand over her heart to the one man she was never supposed to need. Lethal Vows is a scorching romantic suspense novel featuring an alpha ex-Interpol hero, a fiercely capable heroine, explosive chemistry, and a twisting criminal conspiracy set against the glamour and shadows of Singapore's elite.
