Book excerpt: From the legends of Atlantis, El Dorado, and Shangri-La to classic novels such as King Solomon's Mine, The Land That Time Forgot, and The Lost World, readers have long been fascinated by the idea of lost worlds and mythical kingdoms. Read short stories featuring the discovery of such worlds or kingdoms--stories where scientists explore unknown places, stories where the discovery of such turns the world on its head, stories where we're struck with the sense of wonder at realizing that we don't know our world quite as well as we'd thought. Featuring new tales by today's masters of SF&F: Tobias S. Buckell James L. Cambias Becky Chambers Kate Elliott C.C. Finlay Jeffrey Ford Theodora Goss Darcie Little Badger Jonathan Maberry Seanan McGuire An Owomoyela Dexter Palmer Cadwell Turnbull Genevieve Valentine Carrie Vaughn Charles Yu E. Lily Yu
