Edmond Hamilton 
Crashing Suns 

From mighty Canopus, capital of the Federated Stars, to the outer fringes of our great galaxy, the Interstellar Patrol was on the watch. Rogue suns, marauding alien intelligences, man-made comets driven by their makers for the conquest of unsuspecting worlds, diabolical conspiracies hatched in the depths of unmapped nebulae – it was the business of the Patrol’s mighty spaceships to guard against such cosmic dangers. Crashing Suns is the epic account of this future space legion, where volunteers from a thousand worlds man the mighty starcraft of a hundred thousand years to come. It’s interplanetary adventure on the classic scale, by the master hand of Edmond Hamilton. (Goodreads)
