Soulette
Double Trouble
One heart is the trigger. The other is the target.
At sixteen, Alex Rider is used to being a pawn. He's used to the lies, the isolation, and the weight of a world that only sees him as a weapon. But he isn't the only ghost the Riders left behind.
Meet Abigail Rider. Nineteen. Code name: Cheetah.
In the shadows of the intelligence world, Abigail is a legend-the most untouchable woman alive. She is so fast, so precise, and so lethal that no enemy has ever managed to lay a single finger on her in combat. But her "untouchable" status isn't just a skill; it's a fortress. Raised in a sensory void and denied human contact since she was four years old, she has spent fifteen years flinching from the world, a paper-white phantom who has forgotten how to be human.
When a mission in London goes south, the two halves of the Rider legacy are finally slammed back together. But the reunion isn't a gift-it's a death sentence.
MI6 has a secret. Abigail carries a micro-detonator at the base of her brain, and the fuse is hardwired to Alex's pulse. If his heart stops, her life ends. They weren't brought together to be a family; they were brought together to be a contained, manageable unit of destruction.
Now, hunted by Scorpia and betrayed by the agency that forged them, the Rider siblings must survive the frozen ridges of the Brecon Beacons and the cold halls of Chelsea Manor. To stay alive, the "Untouchable" girl must learn to trust the only person she's allowed to get close to, and the "Pawn" must find the strength to break the leash.
They wanted a weapon. They got Double Trouble.
