Michelle Girard never expected three of her former classmates to wind up dead just before their high school reunion. But thanks to the sharp eye of her former crush, FBI Agent Colin Roarke, the scattered rose petals found at the scenes prove the "Reunion Killer" has struck again. Colin, an uneasy war hero, feels a need to protect Michelle, especially when she becomes the killer's latest obsession. Staying one step ahead has always been Colin's specialty, but as his frustration intensifies, so do the very real complications of long-buried feelings. Then Michelle is kidnapped, and clues lead Colin to the foreboding Columbella House, an abandoned Victorian mansion where shrouds of fog conceal dark secrets—and dangerous, hidden desires.
