This is book number 1 in the Delicious in Dungeon series.
Following an adventuring party as they try to rescue their healer in a dungeon where death doesn't stick, this story is equal parts funny and existential. I started the series for the care and thought that Kui puts into the world building, but I stayed for the multi-layered characters and a story line that gets weirder with every turn. You won't want to put this down!
