Fever Crumb has been adopted and raised by Dr. Crumb, a member of the Order of Engineers, where she serves as an apprentice. At a time when women are not seen as reasonable creatures, Fever is an anomaly, the only girl to serve in the Order. Soon, though, she must say good-bye to Dr. Crumb to assist archaeologist Kit Solent with a top secret project. The assignment involves a mysterious room that once belonged to Auric Godshawk, the last of the Scriven overlords, and Fever must help unlock it.

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 their icy strongholds. She finds a mysterious black pyramid full of secrets. It will change her world forever. Scrivener's Moon follows Fever Crumb and A Web of Air to complete one of the most exciting and inventive fantasy adventures series ever recorded for audio.

London is a radioactive ruin. But Tom and Wren discover that the old predator city hides an awesome secret that could bring an end to the war. But as they risk their lives in its dark underbelly, time is running out. Alone and far away, Hester faces a fanatical enemy who possesses the weapons and the will to destroy the entire human race.

The mighty engines of Anchorage have been rusted and dead for years. The derelict city no longer roams the Ice Wastes, but has settled on the edge of the land that was once America. Tom Natsworthy and Hester Shaw are happy in the safety of a static settlement, but their daughter, Wren, is desperate for adventure. When a dangerously charming submarine pirate offers her a chance to escape, Wren doesn't think twice about leaving her home and her parents behind. But the pirate wants something in return - Wren must steal the mysterious Tin Book.

When Tom and Hester's little scrapyard aircraft is pursued by rocket-firing gunships, the ice city offers sanctuary. But it is no safe refuge. Devastated by plague and haunted by ghosts, Anchorage is heading for the Dead Continent.
