William Dietrich, NAPOLEON'S PYRAMIDS: AN ETHAN GAGE ADVENTURE

Great fun, riotous historical adventure with mystery and some myth thrown in. If you liked Indiana Jones, you will probably like this novel set in late 1700s; it's lighter than David Liss but well researched and engaging, with lots of interesting information about Napoleon's forays into Egypt, the Golden Mean, and pyramids. Clearly the beginning of a series.
