One down, three to go

I've just finished rereading The Rest Falls Away, the first book in the Gardella Vampire Chronicles. I am trying to read them all before I get my hands on book five, As Shadows Fade, which comes out March 3. According to Amazon, I should be getting the book a few days after the third, so we'll see if I'm able to finish the first four before then. If I don't, it's not the end of the world. I'd just like a little refresher before I read the final book of the series.
