The Chosen (Night World #5) by L.J. Smith

Rashel's life changed forever at the age of 5 when her path crossed with a vampire. From that moment on, she vowed that she would never be helpless again, that she would rid the world one vampire at a time until she found the vampire who destroyed her world.

Now she is a vampire slayer. Out on patrol one night she rescues Daphne Childs and uncovers a secret slave trade operated by the Night World. In an attempt to bring down the slave trade and discover an unknown vampire enclave, Rashel sets out to get herself chosen as a slave by the vampires. Along the way she meets her soulmate in the last person she ever anticipated - John Quinn - a vampire with a dark reputation.

Together Rashel and Quinn discover that there may be some dissent brewing within the Night World - Lamia vs. made vampires, the Daybreakers vs. vampires who view humans as vermin. Trouble is brewing and even members of the Council, those charged with keeping the peace and enforcing the laws, are in on it.

This book was much more developed that the others in this series and I wasn't left wanting like I was after book #4. I am getting slightly frustrated with this series, however. It is clearly building to something. With all of the cross human/Night World relationships going on, the character cross overs and all the illusions to a coup, I am curious to see how all of these stories are going to intersect. It is clear that this is where the series is going, however 5 books in and we are still being introduced to new characters and there doesn't seem to be any merging going on. I am hoping that happens soon, or I might start to lose interest in this series...
