Burroughs began writing it on February 28, 1929, and the finished story was first published in The Blue Book Magazine as a six-part serial in the issues for April to September 1930.
The story-teller is Ulysses Paxton, protagonist of the previous novel, The Master Mind of Mars, but this story is not about him; rather, it is the tale of Tan Hadron of Hastor, a lowly, poor padwar (a low-ranking officer) who is in love with the beautiful, haughty Sanoma Tora, daughter of Tor Hatan, a minor but rich noble.
Tavia is an atypical Burroughs heroine; depicted as self-reliant and competent with weapons, witty and intelligent, she compares favorably for both reader and Hadron with beautiful but shallow Sanoma Tora, who ultimately shows herself unworthy of the virtuous hero.
With the addition of Nur An, a disaffected Jaharian warrior, and another escaped woman slave, Phao, Hadron's quest becomes more collaborative than Burroughs' usual, although Tavia, in an unsurprising plot development, is revealed to be a princess at the end.
