Jaz & Vayl's steamy vacation on his private island (BTW- I want, I want!) is cut short when Pete asks them to travel to Australia and stop a group of gnomes from wreaking havoc on and ultimately taking out the Canberra Deep Space Complex. With the whole team back together they head to their safe house but then come under attack by the demon Kyphas, who has a contract for Cassandra's soul. Raoul arrives to help out with his demon fighting weaponry and with Bergman's latest invention, a cute but kick-ass robo-kitty, Astral; they just might make it out of this mess. That is, if Jaz can stop the unknown voice in her head from taking over. 
 Like the rest of the series Bite Marks is creative & imaginative with a fast-paced plot that includes lots of twists & turns, action, cool gadgets, laugh out loud comic relief and great characters. Jaz & Vayl have great chemistry and a few steamy scenes but not graphic ones. The beginning of the book is hilarious where Cole meets Jaz off the plane with a jazzy funeral precession for Vayl that includes a golf bag coffin! And Jaz's improve when Vayl starts to awaken, too funny! Cole's quest to pet a kangaroo while down under is also a fabulously hilarious scene. 
 This isn't one of my favorites in the series but still good. I felt here, unlike the rest of the series, there were a few instances when the story dragged and the sub plots were more interesting then the main plot/mission. 
 Also, some of Jaz's inner dialogue got a bit confusing for me, that girls got a heck of a lot of voices yammering on in her head! 
 Jaz's teammates doubt her ability to perform in the mission because of the extra hitchhiker she has peeping in on her thoughts & actions and some of the subterfuge with her team was a bit over my head but since you're reading in Jaz's POV and she is the one having one put over on her I guess that is the point. And some scenes were kind of nasty, like gnome larvae exploding everywhere out of a body. Yuck. Everything came together at the end though leaving some plot points open for future books that I am interested in seeing.
