Dejah Thoris and the Green Men of Mars (Dejah Thoris and the Green Men of Mars #5)

To keep the peace, Dejah Thoris must keep a dreadful secret - the inhuman acts she witnessed and endured at the hands of outlaw Tharks. To reveal such horror would break the alliances that John Carter forged, pitting all of Mars in a race war. But the price of her secrecy grants the brutal Cult of Hok free reign to launch a terror campaign of their own!
