The plot is the most interesting of the series so far because it provides a better in-depth look at the vampire world and the supernatural world in general that the previous books did not offer. The characters also benefit from the plot as well. The main characters become more like-able, The newly introduced characters are very like-able as well, and the sub-characters have a bigger presence as well. The villains of Club Dead are the best the series has to offer so far. 
 The biggest flaw of the book is would involve Sookie's relationship with Bill. There is a certain graphic act that happens between the two of them that is sort of brushed off in this book as if nothing happened. Also, similar to the previous books, feature quite a few annoying and pointless details that are really unneeded. 
 Aside from that, It's been a pretty solid book overall and is by far the best in the series.
