I've read the first one and I have the next seven to read.
First thoughts - it's unbelievably shit. It was a struggle to finish and ended up being relegated to the bathroom as toilet literature. I really hope that the next book is a vast improvement on the first one, otherwise they're going straight to ebay.
The only reason I'm going to read the next one is because I fancy Eric. ... and the vague hope that they get better later on.
Edit: Okay, so the second one is much better and I'm actually enjoying it. Though I do find Sookie to be really annoying.
