Haertic, I'm a Clive Cussler fan myself, mind me asking which book your reading?
I'm currently reading Cussler's "Spartan Gold". I also enjoyed his "Plague Ship" and "Deep Six".
If you like Cussler, I might also recommend you read Lincoln Child's "Deep Storm".
If you like to take your adventures into more exotic/strange/unusual locations you've got to read some James Rollins. He's my favorite at the moment. I love his imagination and the pictures he paints in my mind as I read. I highly recommend his "Subterranean", and "Amazonia", and "Excavation". He has more in this series of books that I still have in queue to be read. I have about 30 new books in a pile and I start reading whichever one grabs my fancy at the moment after I finish a current book.
If you want to stray off into more of a Mystery/Adventure genre, try "The Dark Tide" by Andrew Gross.
I think everybody should read "Kite Runner" by Khaled Hosseini. I don't know what genre you'd call this one. It can be a sad and depressing story, but it really draws you in.
