Crescent Dawn

I liked this book co-written by Clive Cussler and his son Dirk Cussler. In A.D. 327, a Roman galley with extraordinary cargo barely escapes a pirate attack. In 1916, a British warship mysteriously explodes in the middle of the North Sea. In the present day, a cluster of important mosques in Turkey and Egypt are wracked by explosions. What ties them all together? National Underwater and Marine Agency director Dirk Pitt and his team are about to find out, as Roman artifacts discovered in Turkey and Israel unnervingly connect to the rise of a fundamentalist movement determined to restore the glory of the Ottoman Empire. This is the 21st book in the Dirk Pitt series.
