The Reformed Vampire Support Group by Catherine Jinks
I loved this. Loved it loved it loved it. BUY IT!
This alternative vamp tale is told through Nina, a permanent 15-year-old whose funny, snarky view of life is clouded by the fact that she doesn't enjoy being a vampire. She has weekly meetings with other Australian down-under hidden-cover bloodeaters in the Reformed Vampire Support Group, but when one of their own is killed with a silver bullet, it's a race to figure out who the killer is, how to save their undead lives and maybe uncover secrets at the same time.
I loved Nina, I loved the supporting cast, I loved the whole story. I can't say this enough. Catherine Jinks is a genius (previous novel: Evil Genius) and I worship at her feet. If you're looking for witty, funny, sarcastic vampire tales with a dash of unusual romance and lots of adventure... heck, if you like great books, run out and get this one right now. Or Nina will come and suck your blood.
