The Swords of Zinjaban

Blurb

The Swords of Zinjaban is a science fiction novel written by L. Sprague de Camp and Catherine Crook de Camp, the eleventh book of the former's Viagens Interplanetarias series and the eighth of its subseries of stories set on the fictional planet Krishna. Chronologically it is the eighth Krishna novel as well. It was first published in paperback by Baen Books in February 1991. An E-book edition was published by Gollancz's SF Gateway imprint on September 29, 2011 as part of a general release of de Camp's works in electronic form.
As with all of the "Krishna" novels, the title of The Swords of Zinjaban has a "Z" in it, a practice de Camp claimed to have devised to keep track of them. Short stories in the series do not follow the practice, nor do Viagens Interplanetarias works not set on Krishna.
