Ghost (Modesitt)

Bestselling author L. E. Modesitt, Jr. begins his Ghost Books series with Of Tangible Ghosts in a strange alternate reality where ghosts are no longer mere superstition, but physical realities. When two real ghosts and the records of a murdered researcher enter the life of Johan Eschbach, the former spy and present professor finds himself caught with the secret of high-technology de-ghosting, and the whole world, including his former spymasters, try to turn Johan himself into another ghost. A shocking novel of what could happen if the fanatical defense of the environment crossed the line into deadly terror. When environmental consultant Jack McDarvid's boss is killed in a shootout near the Capitol, McDarvid becomes enmeshed in a diabolical plot behind the scenes of the environmental movement.

Professor Johan Eschbach had hoped for a quiet life in retirement from the intelligence service, teaching environmental science and living with his new wife, but an unusual invitation from the Mormon nation of Deseret inexorably drags him back into the spy business, though he isn't quite sure why or for whom. It quickly becomes apparent that he is being used as a pawn in a deadly game of international maneuverings that are leading the world closer to war.

Professor Johan Eschbach's lovely wife Llysette du Boise, a refugee from the burning remains of France and a world-famous vocalist, has been invited to provide a command performance for the Russian Imperial household. Johan accompanies her, allowing him to work on the oil concession in Russian Alaska that Columbia so desperately needs and do some spying on the side. Johan's espionage is carried out against the backdrop of the famous white nights of St. Petersburg, the nearly Arctic midsummer when the sun barely dips below the horizon and the sky seems to dissolve in ivory light. But even the oil shortage will fade to insignificance when Johan discovers what new weapons technology the Russians are developing, a threat even more fearsome than the atomic bombs of Austro-Hungary.
