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!

    Ten of the ships had reached their destinations. Two had failed-and nobody, in the hundreds of years since the disaster, had the slightest inkling of what had happened. ~ ~~ ~ Joneny, a student of galactic anthropology, was assigned the problem. It had seemed routine to him. Just some faster-than-light travel to the two wrecked ships, a bit of poking around, and then writing up his findings. ~ ~~ ~ But he was ill-prepared for what he found in space at the site of the two ancient wrecks. One, the Sigma-9, was not subject to the laws of time-stasis (the only exception to a universal law), and it was covered entirely with a mysterious green fire that shimmered so much that it seemed alive! And the other ship, the Beta-2, was nowhere to be found. Only a fragment of a mysterious poem could possibly provide a clue.

    According to Locus, Hardwired is Walter Jon Williams's "best book to date".Ex-fighter pilot Cowboy, "hardwired" via skull sockets directly to his lethal electronic hardware, teams up with Sarah, an equally cyborized gun-for-hire, to make a last stab at independence from the rapacious Orbitals.

    So being a Colonial Union officer attached to an interplanetary diplomatic mission sometimes means taking a fall. Literally.

    But mankind is too busy hating, stealing, scheming, and killing to care. As luminous green trails of cosmic dust and vapor stream across the heavens, blood flows beneath: nations wage all-out war, bitter strikes erupt, and jealous lovers plot revenge and murder.

After the earth passes through the comet's tail, suffering, pettiness, and injustice melt away. Willie, Nettie, and everyone around them are reborn. They now see themselves and their world in a dramatically new and wonderful way.

    But in a decadent universe where life is cheap and starflight precious, where emotionless conspirators and mind-controlling churches spin webs of intrigue to ensnare whole galaxies, Dumarest's goal seems impossible. For no one knows where his home world lies, no one believes Dumarest was born on a myth called Earth.Earth is lost in an infinity of stars, leaving Dumarest stranded on Gath, trapped in the schemes of a sadistic prince, a dying Matriarch, a corrupt ruler, and the sinister Cyclan--on a world where star storms drive men mad with the song of the spheres and the voices of the dead arise to kill the living. Here the journey begins, and here it may end, adrift on the Winds of Gath.
