Clandestine (adj.) Concealed, usually for some secret or illicit purpose.

Dorcas "Dorky" Shannigan has spent most of her unique life closed off from others. A secret keeps her from showing her face to the world, including Grey O'Toole, an operative who stirs her blood with only the sound of his husky voice. Enclosed in her underground library, she keeps agents informed about evil paranormal forces. But part of her aches to connect more closely with the other agents, although to do so would shatter their understanding of the natural world and possibly put them in peril.

Grey O'Toole loves the silky, seductive sound of Dorky's voice, and many years of chatting with the elusive woman has driven him to the edge of his tolerance. He savors the opportunity to finally meet the woman who has fueled a thousand of his fantasies. One night his dream comes true, and she must ask him for help. For a prehistoric malevolence has found her after years of searching and will stop at nothing to destroy her.
