Greed pulls the archaeologist Matt Carse into the forgotten tomb of the Martian god Rhiannon and plunges the unlikely hero into the Red Planet’s fantastic past, when vast oceans covered the land and the legendary Sea-Kings ruled from terraced palaces of decadence and delight.

Talented enough to co-write The Big Sleep film with William Faulkner and imaginative enough to pen the original screenplay for The Empire Strikes Back, Leigh Brackett is a giant in the science-fiction field, and The Sword of Rhiannon is one of her most popular adventure tales.
