This jumps ahead about six months in the Tracking Trouble storyline (so it could be Christmas).

It’s mostly about a new goblin heroine, so no big spoilers for the main storyline, but there is something that takes places in Tracking Trouble Book 3 (with Matti and Sarrlevi) that is evident here, so if you absolutely want no spoilers, you might want to wait until you’ve finished Book 3.

A cleaned up version of this story will probably get tucked at the end of the final book in the series.
