I recommend anything written by Wilbur Smith! ANYTHING!!! i haven't read one of his books that disappointed me yet. I've read about 10 of his 30+ books.
I must warn you though, that his books are not for the faint of heart. He can become quite graphic at times, and he does have the odd sex scene, but it's done with a classy taste... not like reading a porn mag or anything. He has a huge variety of different books, some are based in Egytian times, some take place 16th century, some are present day, ect... but they are all great reads, i really recommend 'The Courtney' series of his.
bottom line.... Wilbur Smith is amazing, i use to think Tolkien was the king of capturing my imagination, until i stumbled across Mr Smith's work.
