Hello Summer, Goodbye

It was an alien planet - yet not too alien from Earth. It had its differences: its ice-goblins, its curious furry lorin, its thickening water, and its unearthly tides, but for a young man like Alika-Drove thinking of a vacation by the sea these oddities were the norm. But this vacation was to be different. Rax was coming into the ascendant and Rax, that cold second sun, was the equivalent of evil, of Satan and of Hell. And as its time drew near everything began to get warped and sinister... until for Alika-Drove it would be either the harsh brutal end of his innocence or the end of his world forever. RAX is the latest and possibly the most original novel of the very imaginative talent of Michael G. Coney. (from the back of the DAW Books first US edition)
