Not Even Bones by Rebecca Schaeffer, Glamist, and Alai Cinereo is a comic about trust, mistrust, betrayal, and child trafficking, all told through a YA fantasy lens. It's got monsters (unnaturals, so no one's feelings are hurt), love, and enough parent/child relationship issues to fill an afternoon special. Our mileage, as with all things YA, varied, but you should definitely give it a look.
