The Seven-Carat Conundrum: a Teen Spy Thriller, Sarah & Simon Book 2 (Sarah & Simon, Spies)

A forgotten island. Mysterious crown jewels. A plot to steal them both. What have Sarah and Simon stumbled into this time? Twin teen spies Sarah and Simon have a secret, one that could get them assigned to permanent desk duty, or worse. A secret they’ve managed to keep hidden from an entire spy agency. For now. Soon they’re sent to the distant island of Oublie Toire on a new mission. Solve a baffling murder and protect the irritating, self-important, but undeniably charismatic Prince Chance with their very lives… assuming Sarah doesn’t kill him first, herself. But danger lurks in the shadows. Conspiracies swirl around the king of Oublie Toire, a French colony forgotten and abandoned during the chaotic Revolution. For two and a half centuries, Oublie Toire has thrived in isolation, inventing groundbreaking scientific discoveries to transform its desert terrain into fertile land. The kind of discoveries people kill for. Now, the island wants its independence… while France has never had more reason to hang on to it. The rumors about the king could give France the leverage it needs to destabilize the delicate treaty he has negotiated, and only the prince and the mysterious crown jewels stand in the way of a total collapse of negotiations. But soon, the twins uncover an even greater threat, one that no one else suspects. The only way they can prevent all of Europe from making a catastrophic mistake is to reveal the very secret they most need to keep. If you like adventure, unexpected twists, strong girls, snappy comebacks, and ridiculously annoying charming princes, then get ready to join the mission. Perfect for fans of Ally Carter (The Gallagher Girls), Anthony Horowitz (Alex Rider) and Robert Muchamore (Cherub).
