I used to gobble up historical fiction, especially a million years ago when I was a teenager. History piqued my interest from a young age and I loved reading books with these settings. However, as an adult, I've found historical fiction a tougher nut to crack, with it being my most "did-not-finish" genre by a long mile.
I suspect my lack of engagement with historical fiction has to do with my having read a lot of excellent historical narrative non-fiction in college, graduate school and later. Top-notch works from that genre just grab me in a way that fiction often falters. It may sound snotty, but it's true.
However, I keep revisiting historical fiction because I want to revisit that love I once had--it used to thrill me to visit a time period other than my own and feel immersed in the experiences inherent to that time. Recently, I tried out a couple more historical novels, both YA, one a realistic novel set in 1938 Los Angeles, the other a historical with fantasy elements set in the pre-Civil War American South. Unfortunately, I was unable to finish either, but on the bright side, I think they both have audiences who will adore them.
