With a Tangled Skein
Piers Anthony
 Set around the time of World War I, a young Irish (21) woman named Niobe has a marriage arranged for her by her parents. Her husband-to-be is a teenage boy (16) named Cedric Kaftan. She considers him too immature for her, but can find no way out of the marriage. Although Niobe at first hates being married to a "child", Cedric's good nature, kind heartedness, and desire to make his wife happy and safe win her over, and she soon falls madly in love with her husband. Cedric shows that he is an intellectual prodigy. With some prodding and nurturing from his wife as well as from his mentor, Cedric accepts a scholarship to attend college and hone his magical abilities. As he matures and finds his niche in magic and wetland studies, he and Niobe have a child: Cedric Jr. With a bright future certain, and wizardry greatness assured, life in the Kaftan house was happy indeed. Sadly a few years later, Cedric learns of a plot to kill Niobe. Seeing no way to avert it, Cedric leaves school, goes home to Niobe, hastily puts his affairs in order, and sets in motion the only way he can save his wife's life..... by taking her place. On the fateful morning, Cedric wakes up to make love to his wife one last time, kisses her goodbye and goes into the woods to face his destiny. Awakened by gunshots, Niobe learns her husband is assassinated as part of a plot by the agents of Satan. She learns not only of the plot, but that she, and not her husband, was the real target. Upon learning this, Niobe's hatred for having her husband's life cut short, makes her vow to make Satan pay. She is invited to join as an aspect of the incarnation of Fate, three women sharing one physical body. Eager to thwart Satan's plans and to avenge Cedric, she leaves her child with Cedric's cousin and becomes Clotho, the youngest aspect of the three Fates. The three Fates weave the tapestry of life and have disposition over the length of human lives and the pattern they produce. Clotho, the youngest, spins the threads from the substance of Void; Lachesis, the middle aspect, measures the threads and Atropos, the oldest, cuts the thread of each individual human. When she takes the aspect of Clotho, Niobe must journey to the edge of the Void without aid from the other Fates and replenish her stock of thread-material. Because Incarnations do not age, Niobe spends many years as Clotho. She frequently visits her son, who has befriended Cedric's younger cousin, Pacian. Because her lack of aging would be noticed, she takes the form of the grandmotherly Atropos, pretending to be a concerned family friend. One day, the Fates take the two boys to a fortune teller, who gives them disturbing news—each of the boys will have a daughter who will oppose a tangle in the threads of life. However, one of the girls is fated to marry Death, and the other is fated to marry Evil. Niobe leaves the office of Clotho and returns to mortal life in order to marry Pacian, who has matured while she was in office. She gives birth to a daughter they call Orb, at around the same time that her son, who is now a powerful magician, has a daughter called Luna. The two girls grow up together under the magician's protection. At one point the girls and Niobe go on a quest for powerful artifacts that will enhance their natural talents, and Satan takes the opportunity to send demons against them. Although one of the girls is to marry him, he is not interested in a wife who is not evil. Niobe helps the girls to get through safely, though, and Satan's plot comes to nothing. One year after the events of On a Pale Horse, the middle-aged Niobe is asked to join the Incarnation of Fate once again, this time as Lachesis. Satan has arranged to have all three women leave the office at the same time, thus making the Incarnation of Fate inexperienced in all three aspects simultaneously. The current office-holders hope to use Niobe's previous experience as aspect of Fate as an ace in the hole to prevent Satan's current plot from coming to fruition. They learn that Satan plans to cause political turmoil in the UN by having one of his minions plant a stink-bomb. They are forced to waste time by investigating the likely minions one by one, but in the meantime Satan is offering aging political candidates a chance at renewed youth, and the opportunity to start over in their careers, in exchange for their resignation from office. He plans to replace them with his own minions, who would work against Luna. The three Fates realize that their inexperience is a liability, so they seek help. They learn that Niobe's son, the magician, can help them—unfortunately, he is now in Hell. Satan cannot prevent them from searching for the magician, but he can make the quest very unpleasant and one of them must risk her own soul in the process. Niobe is worried that Satan will cheat, so she arranges for the Incarnation of War to supervise the contest. Niobe leaves the Fates' collective body and goes to Hell. She must beat Satan's challenge—a puzzle-maze—in order to get the answers she is looking for. At the end, she finds her son, but Satan has cast an illusion over him. She puzzles out the answer anyway—that Satan's plot can be stopped by the Atropos aspect of Fate: Atropos can cut short the lives of Satan's minions, making his plot futile. Niobe wins the game and is allowed to leave Hell freely.
