Mayflower by Nathaniel Philbrick
I've always been fascinated by the Puritans that first came to New England (being a born New Englander, it's sort of drilled into you...) and actually did a paper on Puritan literature (Doooommmm), so this book is a natural pick for me.
Brother Odd by Dean Koontz
This is the third in his Odd Thomas series and I've enjoyed every one of them.
On Writing by Stephen King ... by far one of the most enlightening books on the writing process I've read.
Check out my all-time favs though.
