Delver

In this fantasy adventure story we follow Temerity Aster, a 15-year-old girl who lives with her large family in a small village of goat herders in the tiny hamlet of Oddgoat. The world she lives is shaken up when random doors to living dungeons appear, including one that has appeared in her cellar.

Now her family must deal with the introduction of "Delvers"-adventurers who are looking to explore these dungeons and escape with treasure. Soon life for her and her family changes forever, and she must face two choices: abandon the only home she's ever known to carpet baggers and sellswords, or carve out a place for herself and her family in this new and dangerous world of delving.
