When a creature dies, its spirit can go looking for somewhere to hide. Some people have space inside them, perfect for hiding. Makepeace, a courageous girl with a mysterious past, defends herself nightly from the ghosts which try to possess her. Then a dreadful event causes her to drop her guard for a moment.
