Books 9 and 10 of Anita Blake series.
#9 Obsidian Butterfly is really good and reminds me of the books towards the beginning of the series. She is paired with Edward and out of town so it is more heavy on plot then sex.
#10 Narcissus in Chains introduces Micah a new wereleopard. This book is sort of the crossing into erotica and the plot is a little thin. I've heard it only gets worse from here. I am dissappointed that Hamilton took this path with her books.
