For well over a half century, Andre Norton has been one of the most popular science fiction and fantasy authors in the world. Since her first SF novels were published in the 1940s, her adventure SF has enthralled readers young and old. With series such as Time Traders, Solar Queen, Forerunner, Beast Master, Crosstime, and Janus, as well as many stand-alone novels, her tales of action and adventure throughout the galaxy have drawn countless readers to science fiction. 

Quest Crosstime:  On an Earth exactly similar to ours geographically, but in which events of history and society took strangely different turns, Blake Walker found himself involved in a QUEST CROSSTIME.

Born in the Earth we know, Blake had become a citizen of that alternate world and thought himself trusted until the mysterious disappearance of his patron's daughters, the rebellion of the time-travel engineers, and the outburst of a plot to use the secret of time to loot a hundred unsuspecting worlds.

Blake's search through alternate Earths, his daring adventures with alien empires and hostile beings, all combine to make this one of Andre Norton's most unusual and exciting novels.
