Turned by Blood

Janine's always been the useless human in her social circle, the one who stays behind while her vampire, werewolf, and Mage friends have all the cool adventures. According to her pals, she's lucky, because society gives supernaturals a hard time. But being Normal is so...boring. And her mother always says she'll never amount to anything.
Or shall she say, being Normal was boring. After a bite from her best friend, Janine finds herself a newborn vampire. And now she can finally kick butt at soccer, stay out all night and cram in more studying to get her grades up. So long as her mother doesn't find out...
But maybe Turning isn't the best thing that ever happened to Janine. The new diet is tricky and so is going back to school. And then she bites someone who just might be a god, and her new powers heighten to the point where she draws the attention of the Mother of All Vampires. That's not a good thing because the Mother has a horrible plan for all the vampires along with humanity, and Janine finds herself at the center of it.
While this is technically the sixth Abnormals Underground book, it can be read on its own and is also the first book of the Janine's Story trilogy.
