Since several of the other book blogs have done a list like this, I thought I'd take a look back at my favorites as well. Out of all of them, only three fiction entries. Heh. (Okay, I have to 'fess...I did enjoy the hell out of the four "Pink Carnation" books by Lauren Willig.)
Inside the Victorian Home, Judith Flander (nonfiction, history)
An Incomplete Revenge, Jacqueline Winspear (mystery)
The Time Travelers and The Time Thief, Linda Buckley-Archer (young adult; arrgh! the third book isn't out until June!!!)
A Short History of Nearly Everything, Bill Bryson (nonfiction)
Wait Till Next Year, Doris Kearns Goodwin (memoir; I hate baseball, but I loved this book)
America 1908, Jim Rasenberger (nonfiction, history)
In the Shadow of the Moon, Francis French and Colin Burgess (nonfiction, space program)
Color, Victoria Finlay (nonfiction)
Only Yesterday, Frederick Lewis Allen (nonfiction, history ["Roaring" 20s])
The Worst Hard Time, Timothy Egan (nonfiction, history [Dust Bowl])
Crusader Nation, David Trexel (nonfiction, history [1898-1920 US])
