The title of this work calls it a workbook.
That's a LIE.
It's actually an indispensible reference for any functional adult who also runs a D&D campaign.
The book covers everything you need to remember to be a DM in the modern world. I love the content, the perspective, and the ease with which it allows me to put together a game.
Good work, Mike!
