Cat longs to get out into the world and find stories. Instead, she's stuck at home with a lot of younger siblings. When family friends invite her to join them at their apartment in Antibes for the summer, she jumps at the chance. And there she finds a whole new world, and meets the eccentric Henry. But is everything all it seems? Who are these people who are being so kind to her, and what's actually going on behind the glitzy façades? This book is essentially a modern retelling of Northanger Abbey, but with added murders.
