Clive Cussler's Lost Empire starts out with the millionaire treasure hunters Sam and Remi Fargo having a simple vacation in Tanzania. On a normal diving trip, they find an old artifact. Suddenly, special forces and a rich person in the background find great interest in them and their discovery. Sam and Remi are intrigued.
This, like other books by Clive Cussler I read before, is a prototypical adventure book for the boy in an adult. Treasure hunting, exotic places, five star hotels, underground caves, special forces, action scenes and historical detective research all combined into a fascinating story. At least if you don't mind history being changed from the real world. Also, I noticed in this book that the couple Sam and Remi is probably as close to an unsexist protagonist couple I have ever read about. While there are some sex-specific traits, like Sam being the science geek and Remi more into art and cultures, and Remi having a recurring preference for nice dresses and hot baths, they both are intelligent, have their fields of expertise, and act as equals in all regards. This is a refreshing change from the typical female sidekick in books that is just there to make the male protagonist look cooler.
All in all, I have to admit I'm simply biased. These kinds of books appeal to me immensely. If you like Indiana Jones style adventure stories and do not mind cliches and some historical inaccuracy, this is for you, too.
