It is Henry's third visit to the Faerie Realm, but this time in a rather different guise and to a rather different kind of place. Prince Pyrgus has stumbled across some mysterious crystal flowers with an apparently formidable secret weapon, and there are rumours of a demon invasion led by Beleth, the Prince of Darkness.
When Henry gets called back to the Faerie Realm to help his friends Holly Blue and Pyrgus, he has to be more resourceful and brave than he could ever have thought possible. When Pyrgus and Holly Blue are confronted with their greatest fear they too have to prove themselves to be courageous beyond their own expectations.
