"This book is hovering between a number of genres in a very interesting way. Part fantasy thought piece, part non-fiction about the practicalities of lairs, and part dungeon master’s guide to crafting great lairs for TTRPG campaigns. All of it comes together to form a very serious book about a somewhat silly subject that I enjoyed quite a lot"
