London is in chaos.
Rue and the crew of The Spotted Custard returned from India with revelations that shook the foundations of the scientific community. There is mass political upheaval, the vampires are tetchy, and something is seriously wrong with the local werewolf pack. To top it all off, Rue’s best friend Primrose keeps getting engaged to the most inappropriate military types.
Rue has got personal problems as well. Her vampire father is angry, her werewolf father is crazy, and her obstreperous mother is both. Worst of all, Rue’s beginning to suspect what they all really are… is frightened.
When the Custard is ordered to Egypt, transporting some highly unusual passengers, Rue’s problems go from personal to impossible. Can she get Percy to stop sulking? Will she find the true cause of Primrose’s lovesickness? And what is Quesnel hiding in the boiler room?
