I listened to this on audio book as background noise while working. I also almost stopped because some of the the accents were difficult for me to get used to. They seriously grated on my nerves in the very beginning. But of course the more I listened I eventually got used to it and it wasn't so bad. 
 Adrian is a shadowspawn, hellspawn? demonspawn? The word they used already escapes me hah! But anyways think vampire but he's one that fights his nature - he doesn't want to drink blood and when he has to it gets it from a cold icky donated blood bag from The Red Cross. He figures he donates to the institution and he's a man in need of some volunteer blood from time to time. Someone has a guilty conscience much? 
 So he and his girlfriend Ellen just split and right about that time Adrian's evil twin sister comes to town and abducts her. Very unfortunate for us audio listeners her name is Adrienne. You know I might even have this backwards since I listened instead of reading it - so my spelling could be wrong here are their names. It doesn't matter really because in the audio it sounds almost freaking exactly the same when pronounced...kind of bugged me to no end. If I would have read it instead of listening I bet it wouldn't have bothered me so much. 
 As we move along Adrian gets pulled back into an organization he had retired from that are out to kill off the evil menace (they don't really do such a great job of it) - and he's off to rescue his kidnapped lady from said evil twin. 
 A few mild concerns: There was a touch bit of overload on info for me in this one but I think if I would have read it instead of listened to it I would have enjoyed it more. Some of the scenarios seems a wee bit convenient but what is fantasy if not convenient? 
 The telepathic talking portion with the long pauses between each word in the narration almost ended things for me entirely and I was a touch close to not continuing with the audio. Can you tell yet that I'm a sensitive freaking listener? 
 All things considered, it looks like it could be a good series so I'm going to continue. Though I'm going to skip book 2 and go straight to book 3 as part of a personal experiment. As I honestly didn't listen with undivided attention to this audio book and it was only given 1/3 of my attention while I went through my normal workday, my review might not be entirely fair. The third book I'm going to actually read in print so we'll see how it holds up to my - trying books later in a series as a 'standalone' experiment.
