Mortal Engines Quartet

The Mortal Engines Quartet is a fantasy novel series by British author, Philip Reeve.
A prequel series, Fever Crumb, set 600 years before the events of the Quartet, was published between 2009 and 2011. In March 2020 Reeve said "too much time has passed since I wrote the other books, it’s hard to go back to that world" and that he did not intend to publish further books in the series.
On November 18, 2020, upon asked whether "Mortal Engines" would be rebooted for the television screens, he responded that, while that would be nice, it seemed unlikely.
