Jondelle (Dumarest Saga 10), by E.C. Tubb, paperback science fiction novel
“‘Earth is real,’ Dumarest insisted. ‘A world old and scarred by ancient wars. The stars are few and there is a great single moon which hangs like a pale sun in the night sky.’
In the quest for his legendary birthplace, Earl Dumarest has traversed galaxies. Now, at least, he reaches Ourelle, a planet close to Earth – out along a far arm of the Milky Way. There he finds Jondelle, a boy who may hold the key to Earl’s search.
But then Jondelle is kidnapped. And Dumarest’s pursuit of the imperilled boy leads him to a city of paranoiac killers – madmen whose terrible violence is always on a hair-trigger!”
