Put on your best trick-or-treat gear to celebrate the launch of a book all about witches, unicorns and goblins. Oh, and about ordinary kids too. The Uncomfortable Glass Slippers is the second in The Strange Sagas of Sabrina Summers trilogy and the author - Michele Clark McConnochie - will be reading from the book. Will it be spooky? Will it be funny? Will it be both? Games like 'Pin the tail on the unicorn' and 'Sabrina Says' plus prizes for costumes too.
