Ahoy there mateys! I say this every time I finish one of these novellas but I seriously could read dozens of books set in the various worlds.  This book starts with a trigger warning / disclaimer by the author and I am very glad because the first part of the book made me heart hurt and me skin crawl.  I could only get through it because of the author's promise.  It was extremely well-written though.  The second part involves Antsy going through her door to a place where the lost things go.  I would have loved being in the shop and digging through all the sections and finding random treasure.  I really enjoyed the markets she goes to and how she handled the other folk in the shop.  It was also nice to get a bit more understanding of how the doors work.  This can be read as a standalone but I suggest ye start from the beginning.  I am glad there are two more scheduled in this series.  Arrrr!
