The Metamorphosis by Franz Kafka illustrated

Gregor Samsa wakes up one morning to find himself transformed into a "monstrous vermin". He initially considers the transformation to be temporary and slowly ponders the consequences of this metamorphosis. Stuck on his back and unable to get up and leave the bed, Gregor reflects on his job as a traveling salesman and cloth merchant, which he characterizes as being full of "temporary and constantly changing human relationships, which never come from the heart". He sees his employer as a despot and would quickly quit his job if he were not his family's sole breadwinner and working off his bankrupt father's debts. While trying to move Gregor finds that his office manager, the chief clerk, has shown up to check on him, indignant about Gregor's unexcused absence. Gregor attempts to communicate with both the manager and his family, but all they can hear from behind the door is incomprehensible vocalizations. Gregor laboriously drags himself across the floor and opens the door. The clerk, upon seeing the transformed Gregor, flees the apartment. Gregor's family is horrified, and his father drives him back into his room, injuring his side by shoving him when he gets stuck in the doorway.

With Gregor's unexpected transformation, his family is deprived of their financial stability. They keep Gregor locked in his room, and he begins to accept his new identity and adapt to his new body. His sister Grete is the only one willing to bring him food, which they find Gregor only likes if it is rotten. He spends much of his time crawling around on the floor, walls, and ceiling and, upon discovering Gregor's new pastime, Grete decides to remove his furniture to give him more space. She and her mother begin to empty the room of everything except the sofa Gregor hides under whenever anyone comes in, but he finds their actions deeply distressing. He desperately tries to save a particularly loved portrait on the wall of a woman clad in fur. His mother loses consciousness at the sight of him clinging to the image to protect it. When Grete rushes out of the room to get some aromatic spirits, Gregor follows her and is slightly hurt when she drops a medicine bottle and it breaks. Their father returns home and angrily hurls apples at Gregor, one of which becomes lodged in a sensitive spot in his back and severely wounds him.
