This is a really wide ranging collection of stories. There are some from her existing worlds (Temeraire and Scholomance), with a fun inclusion of an earlier version of the novel Spinning Silver.
She also plays in some other sandboxes – I really enjoyed the Pride and Prejudice story set in the Temeraire world – it was an interesting twist on that story. There was also a very interesting play on the Ariadne and the Minotaur myth – I liked that quite a bit.
