When the bad fairy Sisygambis escapes from the museum, Briony and Gryff decide to send her far away where she can't cause any more trouble. Petra Petal tells them about the Land of the Lotus Eaters which is the home of all fairies.
The Land of the Lotus Eaters is a beautiful island where time doesn't work properly. Lotus flowers smell sweet but they are dangerous. If you eat them you forget who you are and where you come from. Don't eat the flowers, Briony!
