Scrivener’s Moon by Philip Reeve
The Scriven people are brilliant, mad – and dead…
All except one, whose monstrous creation is nearly complete: a giant city on wheels. New London terrifies the rest of the world, and an army of mammoth-riders gathers to fight it.
Meanwhile, young Fever Crumb begins a hunt for Ancient technology in the icy strongholds of the north. She finds a mysterious black pyramid full of secrets. It will change her world forever.
The final adventure in Philip Reeve’s brilliant Fever Crumb trilogy.
