Madeline Series: The Great Escape
Salem is a half-vampire who wants to live and work quietly in the magic shop with her friends, Edgar, a talking crow, and James, a house gnome. Nylah Lovecraft, a witch, just wants to do her job correctly, even though it is the wrong one and no one else is following the rules. Agent Laurel is famous at Greenhouse, the organization that captures magic folk and never plans to retire. And Julian, a vampire, just wants to find his half-sister and bring her home.
What, you may ask, do all these characters have in common? It's easy. Of course, it all has to do with an eccentric witch who has been dodging her fees to the Designated Offices of Witchcraft.
