Colony - Hugo Wilcken I don't want to give away too much about the story, but I will say 'read it'! (FYI, these days it's a bargain price of $5.98 on amazon or $3.99 on bookcloseouts for those in the US.) I'd definitely recommend it for anyone who loves Heart of Darkness, the jungle feel of Apolcalypse Now, hazy lines between reality and imagination, philosophical works along the lines of Camus (and perhaps a bit of Kafka tossed in). Two of the main themes are escape & reality -- escape from physical places, escape to/from oneself, escape from reality, shifting reality....

This book definitely deserves a wider audience.

A couple of great blog posts about the book:
