The appearance of the warp drive from the long lost Fenrir spaceship triggers an epic quest for Captain Mikhail Volkov.  According to the drive's computers, Fenrir had been lost to hypothetical “nowhere” of subspace, but with the drive's housing covered with coral and sea life, obviously Fenrir has gone somewhere.  Faced with genocide at the hands of the alien Nefrim, humans need a miracle to survive.  On the chance that Fenrir's mysterious location holds such a miracle, Mikhail jumps into the unknown and crashes into the endless blue of the Sargasso Sea. Every ship that misjumped from any race that discovered travel through subspace has crashed into its waters, creating a graveyard of rusting spaceships.  On the Sargasso's great oceans, humans live alongside aliens in uneasy peace.
