She's faced the cannibal Thark, Voro, and he's dead. She's stopped his plot to terrorize Helium and destroy the peace between red and green people. Now, consumed with survivor's guilt, Dejah Thoris does something beyond reckless: joins a team of Thark warriors formerly under Voro's command for a suicide mission. The Princess poses as their slave to infiltrate a savage tribe of green Warhoons trekking across the Barsoomian desert to an ancient, unearthed weapon. Vastly outnumbered, they must stop the Warhoon lunatics from activating it with a psychic in their midst -- and turning it on Helium! Collects the final story arc (issues #9-12) from the "Dejah Thoris and the Green Men of Mars" comic book series, complete with a pin-up gallery featuring the entire gorgeous selection of variant cover artwork.
So basically Dejah Thoris is suffering from a kind of PTSD but is still working to maintain the truce between red men and Thark. Here we get to see Dejah with hair cut short and looking very punk. Although I don't mind the idea of Dejah having her own life outside of her marriage to John Carter, this certainly wasn't the way I would have imagined it. I thought Alan Burt Akers (Ken Bulmer) did this very well with his novel about Delia, Dray Prescot's wife in the Kregen books.
Dejah has gathered her secret team of Greens and chooses to join them on their mission. They join a band of Warhoons that will open the way to a unearthed ancient gun that needs a psychic to function. A series of close calls put them in the Warhoon leader's good graces, but destroying the gun is suicide mission that will claim many lives.
