They made her rename it? The first book should be called Dead Until Dark
It's been a few years since I've read some of them, and I got bored after around four books and side story (from an anthology) in.
If you truly are hooked on the series, or will be, just be aware that she writes stories from her main series for anthologies too, as do a lot of authors in that genre. So you have a lot of collecting/hunting to do.
I wasn't terribly impressed by the show. I hadn't kept up with her book series or heard what the HBO True Blood series was even based off of (didn't have HBO for the longest). I came in on the third or fourth episode one night while DH and his mother were watching it. Recognized it within two minutes and was picking out mistakes.
Does Elvis pop up in the tv show? If not, they're definitely trying to make it too serious - which was the other thing I didn't like about it.
