I know a few people who went to this event last year and found it very inspirational. This year it's being held on 12-14th September, at EventCity, Manchester.
There are a number of fiction workshops and talks planned, led by fiction ed Gaynor Davies and authors Della Galton and Jane Wenham-Jones. Full details here. Note that you will need to book the fiction workshop places in advance, and to do that you need to book a ticket for the main event.
