Robert Harris writes historical fiction. His latest book was "Pompeii" about the Vesuvius eruption in the 1st Century A.D. Most of his books are in the World War 2 timeframe. My favorite book of his is "Fatherland" which regards a murder investigation in 1960s Berlin - but it is during Hitler's holiday season (in the book Germany was victorious). It was an HBO movie in the late 80s or early 90s. Another great book was "Enigma" which was made into a movie with Kate Winslet about 5-6 years ago.
Thomas Harris wrote the Hannibal Lecter books ("Red Dragon", "Silence of the Lambs", & "Hannibal"). The books are better than the movies, in my opinion. I don't think he's written anything recently.
Caleb Carr ROCKS!!! He can just make turn-of-the-(last)century NYC come to life in "The Alienist" and "The Angel of Darkness". "The Devil Soldier" is an excellent biography of an American mercenary (Frederic Townsend Ward) who became a major force to be reckoned with during China's Opium Wars (1850s & 1860s). I got "The Italian Secretary" for Christmas and am working through my nightstand book pile down to it.
The Lemony Snicket series (Daniel Handler)!!! Very imaginative books, and he is a very witty writer without becoming overly cutesy.
Janet Evanovich's Stephanie Plum series are very funny, quick reads.
I like John Irving, Garrison Keillor, David Sedaris also.
