This is a three books collection. Titles in this collection are:
A Darkling Plain,
Fleeing from an Anti-Tractionist sect, the Green Storm, Tom and Hester are left drifting in the frozen Ice Wastes, slowly dying of cold after the Jenny Haniver's engines have failed. They are saved at the last minute, finding Anchorage, a once-beautiful ice city that has fallen on hard times. Crippled by plague, there are barely fifty souls on Anchorage now, and the teenage margravine has made a desperate choice. They are heading for America, the Dead Continent...
In A DARKLING PLAIN, Philip Reeve brilliantly completes the breath-taking adventures that began with MORTAL ENGINES. Wren Natsworthy is enjoying life as an aviatrix but her father Tom is troubled by matters of the heart - the last, shocking, encounter with Hester, and the old wound caused by Pennyroyal's bullet. Meanwhile the fragile truce between the Green Storm and the Traction Cities splinters and hostility breaks out again. Events are set on a collision course as things end where they began, with London...
Anchorage has become a static settlement on the shores of the Dead Continent, and its inhabitants have been living peacefully for sixteen years. But now trouble is approaching - in a limpet sub, and fast. The Lost Boys are back, and they'll do anything to get what they want. Tom and Hester's daughter Wren is their eager dupe, bored and desperate for adventure. When the theft of the mysterious Tin Book of Anchorage goes wrong, Wren is snatched away in the limpet, who knows where. Tom and Hester set off to rescue her, but this is the end of their quiet life on Anchorage. The journey will stir up old needs, old secrets - and send them back into perilous waters...
