The Colonel's Widow?

the long version

In her nightmares, Irina Castle relived the horror of witnessing her husband's murder. For two years she'd grieved his death while running Black Hills Search and Rescue—and privately searching for him. Then he emerged from the shadows and was in her life again...leading her to question everything she'd once believed about the man she loved.Rook Castle, a former air force combat rescue officer, had "died" to protect Irina from a terrorist. He couldn't fault her for not trusting him when he returned on a mission to keep her safe from the danger that targeted her again. Nor could he resist the passion that even death could not erase.
