The first volume in a sequel series for Threadbare.
This new series is set in the same world as Andrew Seiple's previous trilogy, Threadbare, but does not involve the same characters. In the same irreverent vein as the previous one, it follows a young halfling (or rather, the transparently equivalent there) who finds herself involved in... well, big trouble, like the title suggests.
The main theme here is overcoming your limitations, and figuring out that, if you are not going to fit, you are going to live in interesting times. All of which are set in motion by the first volume, and some interesting revelations and antagonists.
Although not strictly necessary for the reading, it is highly suggested to have read the previous trilogy, because some aspects of the story get really enhanced by the contrast to the previous trilogy.
