Voyage of the Space Beagle A. E. van Vogt Panther Books 1973
One of the great original classics of modern SF returns
An all-time classic space saga, The Voyage of the Space Beagle is one of the pinnacles of Golden Age SF, an influence on generations of stories. An episodic novel filled with surprises and provocative ideas, this is the story of a great exploration ship sent out into the unknown reaches of space on a long mission of discovery.
They encounter several terrifying alien species, including the Ix, who lay their eggs in human bodies, which then devour the humans from within when they hatch. This is one of the most entertaining and gripping stories in all of classic SF.
