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. And now there's a ghost inside her. The spirit is wild, brutish and strong, but it may be her only defence in a time of dark suspicion and fear. As the English Civil War erupts, Makepeace must decide which is worse: possession - or death.
