the desperate, take-no-prisoners struggle that led humanity to Halo--the fall of the planet Reach. Now, brought to life for the first time, here is the full story of that glorious, doomed conflict.While the brutal Covenant juggernaut sweeps inexorably through space, intent on wiping out humankind, only one stronghold remains--the planet Reach. Practically on Earth's doorstep, it is the last military fortress to defy the onslaught. But the personnel here have another, higher priority: to prevent the Covenant from discovering the location of Earth.Outnumbered and outgunned, the soldiers seem to have little chance against the Covenant, but Reach holds a closely guarded secret. It is the training ground for the very first "super soldiers." Code-named SPARTANs, these highly advanced warriors, specially bioengineered and technologically augmented, are the best in the universe--quiet, professional, and deadly.Now, as the ferocious Covenant attack begins, a handful of SPARTANs stand ready to wage ultimate war. They will kill, they will be destroyed, but they will never surrender. And at least one of them--the SPARTAN known as Master Chief--will live to fight another day on a mysterious and ancient, artificial world called Halo...

    The title is a play on words, one meaning "the force which pulls" & the other being "extremely serious or important". It was serialized in Astounding Science Fiction, 4–7/53. Its 1st cloth publication was in '54. It was 1st published in paper in '58. Along with the novel itself, many editions (& most recent editions) of the book also include Whirligig World, an essay on creating the planet Mesklin that was published in the 6/53 Astounding. He published two sequels, a '70 novel called Star Light & a '73 short story called Lecture Demonstration. Mission of Gravity was nominated for a Retro Hugo Award for '54.For a profit & adventure Barlennan would sail thousands of miles across uncharted waters, into regions where gravity played strange tricks. He'd dare the perils of strange tribes & stranger creatures--even dicker with those aliens from beyond the skies, though the concept of another world was unknown to the inhabitants of the planet of Mesklin. But in spite of the incredible technology of the strangers & without regard for their enormous size, Barlennan had the notion of turning the deal to an unsuspected advantage for himself--a considerable enterprise for a being very much resembling a 15" caterpillar!
