Finn Baxter and the Gravity Engine

A cloaked ship. A volcanic ambush. A global chase beneath land, sea, and sky.

Finn Baxter and his crew thought escaping with the SeaSilk II—the worlds first cloaking, flying, submersible catamaran—was the hard part. But survival was only the beginning. Back in action with upgraded tech and a mysterious AI-powered dog named Dexter, Finn, Lucy, Sammy, and their MI6-butler-turned-bodyguard James are plunged into a high-stakes mission across the North Atlantic.

Hunted by shadowy enemies and caught in top-secret defense negotiations, the team must navigate erupting volcanoes, undersea graveyards, ice-choked Arctic waters—and their own rapidly changing lives.

When a hidden tracker exposes them to powerful global forces, they must outwit not just one villain, but an entire web of international players desperate to control the ships technology. As the line between invention and weapon blurs, Finn and his friends face impossible choices about trust, power, and the kind of future they want to build.

From secret labs in Louisiana to the ruins of the Titanic, this fast-paced sequel blends near-future science, edge-of-your-seat action, and the heart of young inventors with everything to lose.

Perfect for fans of Alex Rider, Enders Game, and The Mysterious Benedict Society.
