A new science fiction mystery featuring Sub-Inspector Ferrin, from two-time Hugo Award winner Elizabeth Bear.

A woman has vanished. She reported her disappearance in advance.

In the Bangalore, India, of the 2070s, a young woman who is internet-famous enters an empty police station and tells the virtual assistant that her life is in danger. When she disappears out of her own apartment, it's up to Police Sub-Inspector Ferron and her partner to determine whether a crime has even been committed. In a world of enhanced tech and extreme interconnectedness, can someone truly disappear?

To find the answers, Ferron will need to enter a braver, newer world of virtual reality - and deal with the small matter of a herd of tiny, vicious unicorns.
