The Vampire Men of Saturn collects issues 16 to 19 of Warlord of Mars Dejah Thoris. The stories are on roughly the same level as those in the first three volumes. The quality of the art, on the other hand, seems to be declining.
Continuing her self-imposed exile from Helium, Dejah goes wandering in the Northern Arctic region, covering her near-nakedness with a coat that she conveniently leaves open at the front despite her concerns about freezing to death because, really, why would she want to cover her near-nakedness? She's about to be eaten by a six legged Martian polar bear when she's saved by a large yellow man who promptly enslaves her.
Not to be outdone, another studly guy abducts Dejah in the next story. Well hey, Dejah is always nearly naked, so who wouldn't want to kidnap her? Not that I condone the enslavement of nearly naked Martian women, and perhaps the alien vampire who kidnaps Dejah goes a bit far by biting her neck, but maybe the residents of Saturn haven't learned proper etiquette for dealing with nearly naked women. Anyway, on Saturn's moons Dejah pretty much acquires the powers of Wonder Woman, making her even more formidable. And after biting Dejah's neck, the question is, which one will be enslaved: Dejah or the vampire? Biting Dejah's neck, it seems, can become an addictive pleasure.
The art in this volume doesn't seem as sharp or as detailed as it was in some of the earlier volumes. The covers are quite nice, but the interior art is inconsistent. I would give this volume 3 1/2 stars if I could. It's still fun, an Dejah is just as nearly naked as ever, but if the point of the series is simply to show us nearly naked Dejah (and I'm not sure what other point there could be given the overall silliness of the stories), more care should be taken with the art.
