Special Agent Stella Lavender is looking forward to an elegant outdoor wedding, a much-needed change of pace from her adrenaline-fueled work as an undercover drug agent. On the grassy lawn of the Rosscairn Castle B&B, she waits with the couple's family and friends for the ceremony to begin. But one of them has other plans, and as the guests grow restive, the satin-clad bride is dying most horribly. When the sheriff asks for Stella's assistance, she's energized by the opportunity to prove herself. But why would someone kill Justine, the bride, on her wedding day? Even as a paranoid drug dealer seeks to silence her, Stella must unravel a complex knot of obsession, grief and secrets before Justine's murderer claims another victim.
