The Mezmurs - Melissa George - Bog

An old journal, found in the depths of an old mine shaft tell the story of a dwarf's unlikely life. Shail, a young dwarf, gets a job at the best mining company known to his race. It is better than he ever imagined, until his group breaks into a cavern. Gems dot the walls, floor to ceiling, but one dwarf's attention is caught by something in the shadows. He swears he sees a magical, fabled creature, known as a Mezmur. And, not long after, the mine closes, trapping Shail and his team inside, alone... or are they?
