For the first time: the FBI thrillers Riptide and Hemlock Bay together in one volume.

Catherine Coulter's FBI series twists at every turn (San Diego Union-Tribune). In two of her most gripping books-Riptide and Hemlock Bay- FBI agents Dillon Savich and Lacey Sherlock face dangerous threats in both their professional and personal lives.

In Riptide, trouble follows an intrepid reporter to the quiet coastal Maine community, and Savich and Sherlock must face down a KGB agent to find the truth.

In Hemlock Bay, the two travel to Maryland to take down the satanic child-killing Tuttle twins.
