Corvinian Hark comes from a respected line of villains and received top marks at the exclusive university where his ancestors received their degrees in villainy. Alas, human corporations have nearly cornered the market on villainy, and the only internship in London was snapped up by one of his classmates, who quickly took over the Tower by dispatching her predecessor. Left without any good prospects, Corvinian temporarily took a post as caretaker of a safehouse for magical folk needing a bit of help surviving in expensive London. After eight years, Corvinian has noted that his tenants are just as temporary as his job. In fact, the vampire Michael was living there before it was a safehouse a century ago. After slipping into a hospital to kill his phoenix tenant before anyone notices she's not human, and sneaking out with the baby, The Powers That Be, aka his employers, promptly saddle Corvinian with a new and problematic tenant. Analiese is a foreign exchange student from Belgium and more importantly she's unclassified. Corvinian is given six months to figure out her status, in which case he will be promoted, or he's fired. Also, just in case she's actually a generic human, no one can let slip the magical world exists. How hard can it be for ten magical people, if you include Corvinian, to pretend to be normal humans for a few months?
