Celia Graves is a bodyguard in a world where magic parallels technology and the history of magic is taught in college courses. The book gets off to an achingly slow start but quickly gathers steam. If you can get past the first chapter it really does get better. By the second chapter Celia is demonstrating her mixed competence as a bodyguard and getting set up to die. Instead of an untimely demise, she's turned into an "abomination." 
 Celia spends the majority of the book bouncing from one hostile encounter to the next. People want to kill her because she looks like a vampire, or because she's involved in international political markets, or because she just really frosts every female out there. 
 Blood Song suffers from a plot that at times is nearly incoherent. There's just too much that the authors tried to cram in - on occasion with a crowbar. It's nice that they don't feel it necessary to force feed you the plot, but very little is actually explained and everything is a mystery. Even by the end, there remain more loose ends then woven threads. You never do discover how the bad guys killed her best friend or even if they did for certain. There are some romantic threads that are picked up but nothing really happens with them. There's an ex-fiance that Celia can't move out of will-she-or-won't-she. 
 There are too many characters with loosely defined traits and it makes it things a confusing muddle to try and remember whose who. Why do we care about her defense attorney who is in all of six paragraphs or so and has no crucial role in the plot? 
 Celia herself is an example of the issues that plague the novel. She's all over the place. She's a woman who worries about being too girly and feminine, yet she drives a Miata. She doesn't have one major childhood trauma. She has a bucketful: the queen of pathetic mothers, a murdered sister, an implied sexual assault, and a dead-beat dad - just to get started. She's a bodyguard, but couldn't care less about probing into the lives around her. She knows almost nothing about her own supposed best friends. It makes her seem more then a little self-centered, but her actions don't support this. Celia goes out of her way to save people she's just met like the kid at the pharmacy. She has no idea how to fight, even though it's how she makes her living. 
 The last could be an author/editor snafu. Bad guys are able to draw delicate weapons from beneath coats even though they are in the midst of a brawl. A home gas line that has been broken seconds before is somehow in danger of exploding - even worse the broken line is outdoors where the gas would dissipate faster then it could escape. These are easily explained by authorial mistakes or a lack of research.
