Backyard Dungeon 10 (Backyard Dungeon, #10)

There hasn’t been a single dull day since the moment I found the underground world in my backyard. If I’m not fighting monsters and finding loot, I’m out-witting gangsters, dealing with my asshole neighbor, or trying to expand my business. Now, back in my world, it seems someone is trying to rip me off and stall my business, and down in the Twilight, a Goblin king is colluding with the Demon Lord. And it’s up to me to find the solutions to both these problems.
