Dejah Thoris Crimson Genesis Collection [PDF ebook] 

Young Princess Dejah has lived a sheltered existence, growing up behind vast palace walls, guarded by Helium’s greatest warriors. But when the entire royal family is attacked by horrific Kaldane Martians, Dejah narrowly escapes into the wilds of Barsoom, with no recourse but to strike out on her own in an all-out effort to save her kingdom! Eisner Award-winning writer CHUCK BROWN (Bitter Root) is joined by stellar artist EMILIANA PINNA (Red Sonja) for this epic tale from the early years of Dejah Thoris, before the events of Edgar Rice Burroughs’ first classic Mars novel. Collects issues 1-6.
