I've had the whole morning to myself. Lots of time to sit and write....or not.
After reading all my "how to" and "how not to" guides, I've realised that Chapter 7 is completely wrong. I've fallen into the trap of writing a whole load of back-story instead of focussing on what's happening at that moment in time. I've now spent 3 hours wrestling with it and am completely stuck.
Perhaps a nice cup of tea?
Edited to add: after a cup of tea, a quick game of "Gardens of Time" on Facebook and a further two hours, I've finally cracked it. I started from scratch and took the chapter down a new route. I've realised that authors need to be emotionally detached from their story. I was attached to what I'd written - it was my story, not the character's.
Just in time for the girls arriving for tea, bath and an overnight stay.
