I have heard from Jacqui Ji that Kate Magic has some dates set to come to Cornwall during this coming summer!
There will be two 2 hour talks ~ one in Truro on the 8th of July and one in Penzance on the 9th of July. There will also be a workshop with Kate in Penzance on Sunday 10th July. All are taking place at Archie Browns.
That's all I know and I haven't seen any other information online, but I'm guessing you could find out more directly from Archie Browns :)
