Here's the blurb:
The following five stories comprise some of the matter surrounding the life of Lady Abigail Irene Garrett, Th.D., sometime Crown Investigator. They are previously uncollected. One is new; the others were only previously available as bonus chapbooks with the limited editions of various novellas.
Although it was supposed to be for a limited time only a couple of months back, I just found out that Elizabeth Bear's New Amsterdam is still available for 2.99$ here. For the same price, you can get The White City here, Seven For a Secret here, and Bone and Jewel Creatures here.
