A sequel to "Home From the Shore" from 1963. After the land-people had bombed the Castle-Homes of the sea-people, the sea-people had abandoned their known holdings and gone into hiding. Now it seems they are needed as possibly the only ones who can communicate with the newly appeared Space Swimmers.
