"A Sequel that's better than the original."
BLUF (Bottom Line Up Front) - Moving from the Werewolf arena to the Vampire one, I found Blood Bound to be more exciting and captivating than Moon Called. Definitely listen to them in order as there are a few new characters, but this series seems to be furthering each characters development as the storyline progresses.
Plot - WIthout giving away any spoilers the book picks up a couple of months after Moon Called ended. The author does not spend a whole lot of time recapping every aspect of the Werewolf's but touches on the main points and get's right into the new dilemma at hand...Vampires. With the Vampires as the antagonists in this book it interesting to hear yet another author's rendition of the 5 W's with respect to Vampires. Because there was less time spent setting the scene (already taken care of in Moon Called) pretty much the entire 9+ hours was spent solving the crime and further developing the love "triangle" that spawned in the last book.
Narrator - Despite not being one of my personal favorites Ms. King once again does a good job. You'll rarely hear me complain about a narrator being brought back for the follow-on books and with a few exceptions I enjoy her voice inflections and ability to smoothly transition between characters through only using her voice.
