"It has an element of the supernatural," she said, "but not a huge one."
Most recently, Harris has been editing an anthology with Toni L.P. Kelner called "An Apple for the Creature," which was released in September.
The anthology is about supernatural creatures and schools. "But not all these schools are conventional schools, and the characters learn more than the basic ABCs," according to the book description on Harris' website.
With supernatural themes almost commonplace in today's entertainment scene, Harris still stands out as one of the first to combine love and a little bit of blood.
"I was one of the first books doing supernatural mystery and romance," she said. "It was fun to blend everything together, and it wasn't being done."
But is the genre played out? "We'll find out from our readers," many of whom will turn out Saturday to listen to Harris and maybe snag an autograph.
"It's wonderful to see people who like to read in this day and age. It's harder and harder to muster that up," Harris said of seeing throngs of people show up for her various book-signing appearances across the globe.
"They are there because they love books, they love to buy books and they like writers," Harris said. "That is always the most amazing part."
Harris said it's not uncommon to have three generations of a family in a signing line.
"They are talking to each other about issues raised in the books or actions or what they want to happen with the characters," Harris said. "It's great to think that my books are providing a way for families to communicate."
Although Harris turns down about three-quarters of the offers she is sent, she said she couldn't turn down the West Virginia Book Festival.
"I got such a warm invitation," she said. "It was a good time of year for me and it was so genuine."
When asked if she knew Charleston native Sam Trammell -- who plays Sam Merlotte, the bar owner on "True Blood" -- she laughed.
"Well, I know him a little and I like him a lot," Harris said.
Even though she is ending her relationship with Sookie, the HBO television show "True Blood" has just wrapped up its fifth season and will be back for a sixth season in the summer.
Harris said she is "very happy" with the result of the show.
"It would be hypocritical of me to regret the deal I did," she said, "because HBO has boosted my sales so enormously."
In fact, everything she has ever written is currently in print.
"That's great and rare," she said. "More people are reading my work, and just reading, period. It's absolutely great. To get people reading is every writer's dream."
Harris said the "True Blood" "story lines are great," even though they are different. "I think [director Alan Ball] and his writing team are very creative."
Her favorite liberty Ball took with her beloved Southern series is the introduction of baby vampire Jessica, the progeny of Sookie's first vampire love, Bill Compton.
"I enjoy seeing their relationship and how it works with Bill," Harris said. "She is a good foil for his character."
Harris will speak at 2:30 p.m. Saturday in the coliseum at the Civic Center. She will sign books in the coliseum from 12:30 to 2:30 p.m. Saturday and then again immediately after her program, until 4:30 p.m.
Because of time limitations, Harris has placed some restrictions on the book signing. She will sign only one book her person, with no personalization, according to Book Festival officials. People who want their book signed will receive numbered tickets as they enter the coliseum. Groups of people will be called via ticket number to have their book signed.
The West Virginia Book Festival is presented by the Kanawha County Public Library, the Library Foundation of Kanawha County, the West Virginia Humanities Council, The Charleston Gazette and the Charleston Daily Mail.
