Back in June of 2013, I did some content writing for the Gamebook Holdfast: Record of the Dwarven Kingdom Volume 1 (originally titled Holdfast: A Gamebook of Dwarven Vengeance on the Kickstarter page). I received my copy of Holdfast in December 2013, and have been showing people it since then. A lot of people have asked me where they could get a copy of the gamebook; unfortunately it was only available to the people who backed it on Kickstarter. But today, that all changed – Holdfast is now available as a PDF on DriveThruRPG!
According to the Kickstarter update, so far only the main book is available on DriveThruRPG. But Black Chicken Studios has plans to release the add-on material over the next couple of months as well.
