They call it … THE FALL. The center of London – a perfectly circular section of it, two miles in diameter – has vanished from the world, shifting from its position in space and time. It has wound up in a place where there is no natural light. And everybody – tourists, office workers, everyone – is stuck. Try reaching out into the surrounding blackness and your hand dissolves. Try calling out – you get no answer. And that is frightening enough, but now vicious monsters from mythology – harpies, Gorgons, and even were-creatures – have started to appear, roaming the city’s roofs and streets. No regular person can possibly defend these millions of trapped souls from such beasts. But there is one woman in all of Inner London who is considerably more than normal. Supremely athletic and superbly fast, and armed with weapons nobody has ever seen before. No one knows where she came from, but everybody knows her name. They call her … RAYVEN BLACK.
