High Noon by Nora Roberts
Police Lieutenant Phoebe MacNamara found her calling at an early age when a violently unstable man broke into her family’s home, trapping and terrorizing them for hours. Now she’s Savannah’s top hostage negotiator, who puts her life on the line every day to diffuse powder-keg situations.
After watching her talk one of his employees off a roof ledge, Duncan Swift is committed to keeping this intriguing, take-charge woman in his life. Phoebe’s used to working solo, but she’s finding that no amount of negotiation can keep Duncan at arm’s length. Especially when a man throws a hood over Phoebe’s head and brutally assaults her—in her own precinct house—and threatening messages begin appearing on her doorstep. Duncan backs her up every step of the way, as she establishes contact with the faceless tormentor who is determined to make her a hostage to fear—before she becomes the final showdown.
