What to read after A Son of the Sun?

The Willi-Waw lay in the passage between the shore-reef and the outer-reef. From the latter came the low murmur of a lazy surf, but the sheltered stretch of water, not more than a hundred yards across to the white beach of pounded coral sand, was of glass-like smoothness. Narrow as was the passage, and anchored as she was in the shoalest place that gave room to swing, the Willi-Waw's chain rode up-and-down a clean hundred feet. Its course could be traced over the bottom of living coral. Like some monstrous snake, the rusty chain's slack wandered over the ocean floor, crossing and recrossing itself several times and fetching up finally at the idle anchor. Big rock-cod, dun and mottled, played warily in and out of the coral. Other fish, grotesque of form and colour, were brazenly indifferent, even when a big fish-shark drifted sluggishly along and sent the rock-cod scuttling for their favourite crevices.
