Living or dead, every soul is promised a certain amount of time, and when Jenna passed she found a heavy debt of time in her record. Unwilling to simply steal that time from the living, Jenna earns every day she leeches with volunteer work at a suicide prevention hotline.

But something has come for the ghosts of New York, something beyond reason, beyond death, beyond hope; something that can bind ghosts to mirrors and make them do its bidding. Only Jenna stands in its way.

Dusk or Dark or Dawn or Day is a new standalone urban fantasy novella from New York Times bestselling author Seanan McGuire.
