h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

First off, David and his family live in Labrador. The government of his civilisation is located on the island of Newf (which we never see).

The people of Labrador are not really struggling for control amid the ruins. Although Wyndham makes reference to a lawless history, it is obvious that their society is highly stable and politically developed. The government has even started to take a more liberal attitude to the mutants, which David's father disapproves of.

Other than that this is an excellent entry

What would three themes be for this novel, The chrysalids?

Themes? Um... just the usual Wyndham ones I'd say; the struggle to survive, the inability of radically different forms of life to coexist peacefully...

Zagreb: cheers for your thoughts (sorry for not responding sooner, BTW). The 'struggle in the ruins' comment was meant metaphorically rather than literally. I take your point about the sophistication of the norm government, but in terms of its presentation in the book this is still a state which routinely mutilates and exiles mutant human beings and is so concerned about the rise of the telepaths it raises an army to hunt them down. Certainly from the point of view of the telepaths it is a primitive and retrograde body that by its very existence is a deadly threat to them.
