Sons and Lovers opens with the marriage of Gertrude and Walter Morel in a Nottinghamshire colliery district. She is careful, principled, and a little above her station; he is a warm but heavy-drinking miner who soon disappoints her over money and conduct. Early quarrels harden something in her, and the warmth she expected from marriage curdles into endurance. The pit, the rows of miners' houses, and the surrounding fields form the close physical world the family lives in.
Denied a true companion in her husband, Mrs. Morel turns the force of her feeling onto her children. Her eldest, William, is bright and rising, and she lives in his progress; when he goes to London, takes up with a shallow fiancee, and then dies young of illness, she is nearly destroyed. Only when Paul falls dangerously ill does she rouse herself again, and from then on, as Lawrence puts it, her life roots itself in Paul.
Paul grows up artistic and sensitive, working as a clerk and painting in his spare hours. He forms a long, troubled attachment to Miriam Leivers, a devout, inward farm girl who shares his love of ideas and nature. Their bond is intense but strained: he feels she wants his very soul rather than him, and his mother, jealous, believes Miriam will absorb him entirely. Paul keeps drawing close and pulling back, cruel by turns, unable to resolve what he wants.
He then takes up with Clara Dawes, a separated, older suffragette, and finds with her the passion Miriam could not give him. Yet that affair too reaches a limit, because Paul will not hand over his whole self in marriage to anyone. Clara drifts back toward her estranged husband Baxter, whom Paul, oddly, comes to respect. Through all of it the strongest tie remains the one to his mother, who he tells plainly he will never meet the right woman while she lives.
The last movement is Mrs. Morel's long, painful death from cancer, hastened at the end by the morphia her grown children give her. Her death leaves Paul hollowed out and adrift, drawn toward the nothingness he feels her gone into. In the closing lines he refuses that pull: clenching against grief, he turns away from the darkness and walks toward the glowing town, alive and alone.
