Virtues of Purity

What's the going rate for a 19-year old Fae at a blood auction? I was supposed to charge my batteries back home for Christmas vacation. Delusional, I know. Out of nowhere, an Avalonian knight shows up on our doorstep to warn us about a dangerous fugitive he believes is after Mum. Something to do with her pure Morgana blood. Needless to say that any kind of relaxation went down the drain after that. In the middle of it all, my best friend, Charlie, uncovers an underground market for PureX-a drug made from pure-blooded Magicals. We can't leave well enough alone, so of course we decide to dig deeper. What we find makes even my Magical blood freeze. I'm about to discover how much my blood is worth, and the price of that knowledge might be more than I can handle.
