The menace in this story consists of dust from the tail of a comet. It consists of a colloid, analogous to smoke, that incorporates an unknown transuranic element. That element has a great affinity for metal surfaces and it weakens their surface tension, thereby enabling rapidly moving parts to cold weld themselves into solid rigidity.In the town of Mayfield high-school senior Ken Maddox is among the people fascinated by a giant comet whose path is just grazing Earth’s orbit. For the next four months Earth will float within the comet’s tail and on the first night of that sojourn Ken’s car and others begin to have problems with overheating. The next day almost all of the cars in Mayfield and other cities across the country have overheated and then refused to start. Soon all machinery is seizing up, its moving parts cold welded to each other. Because the effect is happening all over the world, people begin blaming the comet.
As the disaster becomes progressively more serious, Ken and his friends in the high school’s science club prepare to study samples of the fused metal at the local college, where Ken’s father teaches chemistry, and to try to get a sample of what the comet is putting into Earth’s atmosphere. While they work, Mayfield is cut off from the outside world and the mayor and the sheriff impose rationing against the anticipated shortages.
After a short stint in a wood-cutting crew bringing in fuel for the coming winter, Ken is called to assist in the work at the college. Along with his friends and the other scientists, he helps with experiments aimed at identifying the cause of the cold-welding phenomenon. A spectroscopic look through a telescope, compared to spectrograms of the affected metals confirms that the comet is the source of the trouble. At the same time Ken and his friends make contact with several ham radio operators around the country, intending to share information.
Little by little, as civilization crumbles around them, the Mayfield science team learns about the comet dust and how to protect machinery from it. One by one, the radio contacts cease as violence sweeps over the metropolitan areas, but aided by a clue from Berkeley just before it was destroyed Ken’s father devises a compound that will decontaminate metal surfaces. A failed attack by marauders attempting to rob the town and a flu epidemic decimate the population, but Ken has an idea that using ultrasound will coagulate the comet dust so that it will fall out of the atmosphere. Egged on by a pair of fanatics, a mob burns the college, but not before the knowledge of the ultrasonic coagulators has been shared. With people in more and more areas building coagulators and decontaminating metal parts, people around the world begin the slow and painful process of rebuilding civilization.

Question: What does Ken help with to prepare for the coming winter?
Answer: A wood-cutting team.

Mademoiselle de Chartres is a sheltered heiress, sixteen years old, whose mother has brought her to the court of Henri II to seek a husband with good financial and social prospects. When old jealousies against a kinsman spark intrigues against the young ingénue, the best marriage prospects withdraw. The young woman follows her mother's recommendation and accepts the overtures of a middling suitor, the Prince de Clèves. After the wedding, she meets the dashing Duke de Nemours. The two fall in love, yet do nothing to pursue their affections, limiting their contact to an occasional visit in the now-Princess of Clèves's salon. The duke becomes enmeshed in a scandal at court that leads the Princess to believe he has been unfaithful in his affections. A letter from a spurned mistress to her paramour is discovered in the dressing room at one of the estates—a letter actually written to the Princess' uncle, the Vidame de Chartres, who has also become entangled in a relationship with the Queen. He begs the Duke de Nemours to claim ownership of the letter, which ends up in the Princess' possession. The duke has to produce documents from the Vidame to convince the Princess that his heart has been true. Eventually, the Prince de Clèves discerns that his wife is in love with another man. She confesses as much. He relentlessly quizzes her—indeed tricks her—until she reveals the man's identity. After he sends a servant to spy on the Duke de Nemours, the Prince de Clèves believes that his wife has been unfaithful in more than just her emotions. He becomes ill and dies (either of his illness or of a broken heart). On his deathbed, he blames the Duke de Nemours for his suffering and begs the Princess not to marry him. Now free to pursue her passions, the Princess is torn between her duty and her love. The duke pursues her more openly, but she rejects him, choosing instead to enter a convent for part of each year. After several years, the duke's love for her does finally fade, and she, still relatively young, passes away in obscurity.
