Canny Comic Con events are usually hosted by Newcastle City Library.
Newcastle City Library is brilliant. It has a great stock of graphic novels, and is right in the centre of Newcastle - 10 minutes walk from Newcastle train station and less than 5 minutes walk from Monument metro station. Click here for more info! Or click here for map!
You don't have to join the library to attend or anything, but hey, if you want to, it's really easy.
