In Another World, I Must Train my Dungeon: A LitRPG Adventure (Paperback) (ISBN-13: 9798841248514)

Shana had a big summer: With the help of her best friends and a Hero from another world she's conquered dungeons, leveled up, defeated a small cult of evil Sorcerers, and looted hundreds of thousands of dollars' worth of gold. But maybe the greatest treasure was the dungeon core they found.

With it, Shana and her friends can build a dungeon of their own, one that will reward them gold and experience for defeating enemies. But that's only if they can figure out how to make it grow. There's also one other little problem. The dungeon core they "found" had previous owners who are none too happy that it's gone missing, and who will stop at nothing to get it back.
