Co-creator of the Fighting Fantasy series Ian Livingstone is going to be Guest of Honour on the day, and will be talking to Olly Mc, of the StoryMaster's Tales, about his gamebook work, which spans almost four decades.
You can get involved by letting know what you want Olly to ask his interviewees on Thursday, and the place to post them is here.
The day's festivities will conclude with a Virtual Beer-o, hosted by James Aukett, which will be kicking off at 8:00pm.
A number of companies have special offers lined up for the day, including Branching Narrative, so you will be able to pick up Deathtrap Dungeon: The Interactive Video Adventure at 50% off!
So keep an eye on the International Gamebook Day Facebook event page and join in the Fighting Fantasy fun on Thursday.
