Barbarella / Dejah Thoris (Barbarella / Dejah Thoris #2)

The Femmes from the Future find themselves on a world entirely covered by oceans. That's no big deal, what with Earth 70% covered, but for the desert-born Dejah of Mars, some water wings are needed, stat! Really, though, the endless depths are the easy part... it's the creatures lurking in the unknown that are the real threat, especially the intelligent ones!
