Young married private detectives, Debbie and Jeremy Hadley, discover that Debbie's family, the Danforths, have a family secret. Grandma Marie Danforth summons them because she fears that alienated family members and underworld characters will attempt to wrest control of the secret from her. The history of the secret begins at the American Civil War Battle of Gettysburg and develops through a century and a half of Danforth family twists and intrigues. Although written as a continuous story, Impending actually is two novels in one: the saga of how the secret developed from its inception to the present day, and the mystery of how to counter multiple attempts to hijack it. Impending is history and mystery all-in-one. Debbie and Jeremy team with police from two cities to unravel the mystery and reach its surprising conclusion.
