Plague Ship - Andre Norton - Bog

There were no mountains in this section of Sargol-the highest elevations being rounded hills tightly clothed with the same ten-foot grass which covered the plains. From the Queen's observation ports, one could watch the constant ripple of the grass so that the planet appeared to be largely clothed in a shimmering, flowing carpet. To the west were the seas-stretches of shallow water so cut up by strings of islands that they more resembled a series of salty lakes. And it was what was to be found in those seas which had lured the Solar Queen to Sargol.
