Lagrange Five 

The Wide syndrome It is the not-too-distant future. The space colony Lagrangia, on the moon’s orbit, is an idyllic utopia of parks, mountains, streams and blue skies. Lulled by its beauty, citizens can sometimes forget that the 'stream’ are recycled water, and the 'blue skies’ are titanium strips bound together. But there are a few who can never forget. There are the victims of the Wide syndrome – a terrifying form of contagious, claustrophobic madness that can strike anyone – at any time – on Lagrange Five.
