… because there are a few others deserving of mention:
Myself & the Other Fellow: A Biography of Robert Louis Stevenson by Claire Harmon. Everything you could want in a literary biography.
Defining the World The Extraordinary Story of Dr Johnson's Dictionary by Henry Hitchings. Clear, concise and filled with fascinating information not only about the wonderful Dr. Johnson, but much, much else besides.
The Traveler by John Twelve Hawks. I have it on good authority that teenage guys not inclined to read much have a hard time putting this one down. A little goofy, but pretty riveting.
State of Fear by Michael Crichton. Dan Brown should read this just to see how a real pro writes a thriller. Devout environmentalists will rend their garments over Crichton’s blasphemy, but he’s got charts and graphs and a lot of other data to support this thriller’s premise.
The Rosary Girls by Richard Montanari. Complex, effective, and often genuinely creepy thriller quite accurately set in Philly.
