A Land Fit for Heroes Series by Phillip Mann

The first novel in a series set in modern Britain still ruled by the Roman Empire. Technology is advanced, but different from anything we could recognize. Much of the island is still thickly forested, the Roman towns linked by high-speed tubular transportation systems.

This story is the second in a series set in an alternative modern Britain that is still ruled by the Roman Empire. Three young people fleeing Roman rule take refuge in the forests and the village of Stand Alone Stan, where they find that the ancient Britons have survived and magic still exists.
