The problem is, I want to love these books - I love most urban fantasy books, these are reasonably well written, I should therefore enjoy them. 
 My problem is, ironically, that they just are not believable enough for me. When reading urban fantasy one generally does need to suspend their disbelief - I get that, I am very willing to throw away what the world tells me and believe that vampires and werewolves live amongst us, and I am even willing to believe that the vampires organize themselves into glorified fraternity/sorority houses and even when they are over a century old many choose to live dorm room style with their brothers/sisters. Heck, I can even believe that a master vampire chooses to make his house wear jerseys to identify themselves - even if that would create a huge laundry problem in my opinion. What I cannot believe are characters who do not seem to use common sense or logic on a regular basis. 
 It may also be that the author sometimes contradicts herself, or tries to go back and change details that were established in earlier books - and for someone like who tends to be detail oriented, that can be frustrating.

 For example, in the first book of this series the main character is brought back to her home after she was turned into a vampire and part of her 'welcome to the lifestyle' package was some blood from Blood4You stashed in her fridge which also came with a 1-800 number to call to order more. Now logically this means that any vampire (or creepy human) can order some blood and have a snack whenever they wish. However, in this book, Merit and the rest of the Cadogan House are suffering because the receiver sent from the GP has cut their blood supply by 40%. First of all, despite having cut the blood supply, no one, not even the new master, seemed to have put any policy in place to monitor how much people were drinking - I am assuming that there would be some vamps who may need more and some who may try and sacrifice for others, etc. Basically there was no way for anyone to make sure that there would be enough blood for an emergency or anyone monitoring to make sure that everyone was at least getting something. But that is just bad planning (especially if you consider that many of these vamps have supposedly been alive for over a century), I honestly think the author has something against bureaucracy - even the necessary kind. Somehow, it never occurred to our heroine to just order some blood on her own and stash it at her friend's house. Now if the author had said that the Receiver was preventing them from ordering blood on their own, I would have accepted that - but glaring loopholes like this just bug me. And they bug me more when the characters cannot seem to think slightly outside the box.

 Most of the book fell along the same lines as the rest of the series, somehow all older and more experienced vampires/other supernatural miss the obvious issues that Merit sees - often using her uncanny ability to be in the right place at the right time. Again, any available male somehow falls for Merit. I really want to enjoy these books, but the characters need to learn how to think critically - after hundreds of years of undead life maybe they have just given up and decided to let the younger vamps do all the work.
