Lang Reilly's friend, multibillionaire and entrepreneur Sir Eon Weatherston-Wilby, is unveiling some 4th century parchments at the British Museum. Unbeknownst to Lang, there are powerful forces working to destroy the parchments, and during the evening, they strike, taking Eon and the historical documents.

When Eon turns up murdered, Lang decides he must track down the people responsible. To do so, he needs to find the parchments and have them deciphered. Whatever information those documents hold, someone wants hidden and is willing to go to any lengths to keep it that way. As Lang begins his investigation, he is struck down and left fighting for his life.

When Gurt arrives back in the U.S., Lang discovers he has more to live for than ever before. And if he's ever to have peace and happiness again in his life, he will have to find Eon's killers or spend the rest of his life on the run. Lang and Gurt are pursued across continents, Turkish islands, through cities, hotels, markets, mosques, and the backwoods of Georgia by law enforcement officers and killers, surviving by the skin of their teeth.

Gregg Loomis is a star in this genre. His fourth book in the Lang Reilly series is like a roller-coaster ride, as nail-biting and action-packed as the first three. Loomis ups the ante in THE COPTIC SECRET, bringing Lang something he'd all but given up on. I couldn't put this book down. A highly recommended read.
