What’s an older sister to do? It’s not all fun fairs and ice-cream. Well, it is – but that’s beside the point. When one is in Luxembourg, there is a certain standard to maintain, and vacationing with Elves and Vampires is just so old school. But can Alex convince her younger sister, Jackie, of that? No, of course not, so she may as well get used to it. But deep beneath the ancient city of Luxembourg there lies a secret. The Vampires believe it is protected by the Elf. The Elf believes it is protected by a prophecy concerning Alex and Jackie. And the sisters? They believe shoes in Luxembourg are too expensive. Why are the Vampires going toe-to-toe with an Elf for the pleasure of the sisters’ company? Why does the Elf think Alex and Jackie can sing? And just who let Sir Walter Raleigh and the Conquistadors into this story? To answer these questions will take all of the sisters’ cunning, bravery and imagination, as well as some souvenir shopping. Because this is the Elf of Luxembourg and this is an Alex and Jackie Adventure.
