So, what can you expect from this issue? We offer a diverse collection of essays and reflections related to departure, abandonment, refuge, memories and nostalgia. Head over to page 15 for a critical insight into Brasilia, a city which was entitled the '1000 days project'.

Our own editor Christopher introduces his personal documentary series on abandoned chairs (page 6) - what could their stories be? Meanwhile, editor CK explores his fascination for small-scale thresholds in this poem 'When does a door become a window' on page 11.
