Andre Norton

Voodoo Planet is the third in a series of novels featuring the adventures of Dane Thorson and the spaceship Solar Queen, written in the 1950s by Andre Norton under her male pseudonym, Andrew North. In this installment, Dane and his shipmates land on the safari planet Khatka, settled by African refugees of an atomic race war on Earth. They soon face off with a witch doctor seeking to take over the planet.
This short work was originally published as a double title paperback by Ace Books in 1959 along with a reprint of Plague Ship, the second novel in the series. Norton followed it with a sequel ten years later and then co-authored a revival of the series in the 1990s.
