The Hunt for the Golem is a PDF mini-campaign for Frostgrave. It features three new scenarios, a unique monster, and a few new treasures. It will probably be especially interesting to Enchanters and other construct lovers. I originally wrote it as a part of the Frostgrave 'Nickstarter' pre-order campaign. Now, Osprey have put it up for sale so that everyone who wants can get a copy. It is currently available as a PDF on Wargames Vault. It's a US company, but I'm pretty sure it will sell to anyone anywhere. It will also be for sale on the Osprey website soon. A kindle release is also planned, but I'm not sure of the time scale on that.
So, if it sounds like something you might like, head over to Wargames Vault! I have purchased several ebooks through Wargames Vault in the past and always found them a top-notch company.
