Chapters 1-10Chapter Summaries & Analyses

Chapter 1 Summary

Isaiah, a tiny mouse, and his 96 siblings try to escape from the terrible place they’ve called home. As the youngest and smallest, Isaiah follows his brothers and sisters, believing they are heading toward someplace safer. Their escape route leads them through a tiny crack into the outside world, a place none of them have ever been before, and Isaiah is overwhelmed with fear. Their path is obstructed by a garbage bag, which causes the family to scatter. In an attempt to keep up, Isaiah takes a shortcut but gets trapped in the garbage. He frees himself after several frantic attempts but now finds himself alone with no sign of his family. He jumps into a nearby sewer drain, alone and scared.

Chapter 2 Summary

Isaiah hears a siren and sees flashes of red light from an alarm. Despite his fear, an inner voice urges him to keep moving, and he relies on the agility and skills that his mother taught him to navigate the storm drain. He follows a shaft of light up into an alley filled with trash. He slips on a banana peel and skids through a narrow opening, after which he overhears two humans arguing about the mice’s escape. To escape again, he climbs a building and crosses a utility line. He calls out for his brothers and sisters, but gets no response.

Chapter 3 Summary

Isaiah hears the humans counting the captured mice, confirming that his entire family, including his siblings Abe, Winnie, and Benji, have been caught. Isaiah narrowly avoids detection and heads in the opposite direction from the humans. He believes that one of the other mice, Benji, will eventually devise another escape plan. Until then, Isaiah must fend for himself, and he decides to find a hiding spot where he can wait. Despite his intelligence, Isaiah admits to being a “scaredy-cat.” The mere thought of “cat” causes him to panic and fall from a power line, though he fortunately lands in a pile of leaves. He plays dead for a moment, hoping to avoid predators or humans.

Chapter 4 Summary

Isaiah, now alone, has two choices: return to the Horrible Place to be with his family or continue to run and hide until they escape and find him. Isaiah chooses the latter despite his fears. He leaves the tree line and enters the suburbs, a place he has only read about. He sticks close to curbs and gutters, wary of danger from the many cats he sees in windows, and searches for food. This leads him to a trash can filled with discarded food; he finds grapes, bread, and cold oatmeal. Feeling fortunate for not returning to the Horrible Place, he enjoys his meal until he notices something nudging the bin. He peeks over the edge and sees a rat.

Chapter 5 Summary

As Isaiah watches from his vantage point, a group of giant rats emerges from a nearby sewer drain, attracted by the scent of the food. They start bashing the trash can, trying to topple it and get to the food and Isaiah.

Isaiah realizes that the rats, while large and intimidating, lack his intelligence. When the lead rat notices him and seems to relish the idea of making a meal out of him, Isaiah uses his ability to speak human words. He repeatedly shouts, “KIBBLE!” This startles the rats, who flee to the sewer.

Chapter 6 Summary

After the rats are gone, Isaiah grabs a piece of green bread and continues his journey. He follows the road but encounters a sphynx cat named Lucifer, who circles him. Isaiah again uses his trick of shouting to confuse the cat, then dashes up a driveway. Lucifer chases him and traps him in the shrubs under the porch, where it bats him around like a ball while laughing menacingly.

Chapter 7 Summary

When Lucifer prepares to swat Isaiah again, the mouse curls into a tight ball. Upon being struck, Isaiah rebounds off the brick wall and headbutts Lucifer in the stomach. He then bites the cat’s hind leg. Lucifer screeches in pain, allowing Isaiah to escape through a flower bed and around the house to a small hole in a fence that Lucifer cannot fit through. Isaiah lands safely on the other side in a mulch bed beneath fruit trees. He briefly munches on an apple while contemplating his next move and acknowledges it is dangerous outside for a bright blue mouse.

Chapter 8 Summary

Isaiah is lured to one of the houses by the smell of a freshly baked apple pie and peeks through the pet door. Inside, he finds a large woman wearing a flour-dusted apron. She spots Isaiah and throws a rolling pin at him while shouting insults. Isaiah retreats, stung by being judged and hated without reason. As night falls, he grows tired and cold and seeks shelter. He finds a hollow space in a cinder block under a house and gathers leaves, pine needles, and moss to make a bed. Though physically cozy, Isaiah is lonely without his family to huddle with for warmth. He recites the names of his siblings in his head, which lulls him to sleep.

Chapter 9 Summary

Isaiah wakes up feeling unusually rested. His growling stomach forces him to get up. After he realizes that he must find food on his own, he sets out to scavenge the sidewalks for another trash can. As he crosses the lawn, he is startled by the loud sound of the garbage truck collecting the neighborhood’s trash. He hides and watches helplessly as the truck dumps all his potential food into its compactor. When it leaves, Isaiah enters one of the overturned trash cans and finds a small puddle of slop at the bottom. Though it smells terrible, Isaiah reluctantly eats it.

Chapter 10 Summary

Isaiah struggles to eat a chunk of mystery meat covered in spoiled gravy. As he contemplates gathering nuts and berries, he is interrupted by a beautiful, distant song. The garbage barrel amplifies the angelic soprano voice, which reminds him of the lullabies his mother used to sing. He realizes the singer is a mouse, as mice are among the few mammals other than humans capable of carrying a tune. Moved by the enchanting song, Isaiah decides to find its source. He cleans himself up by rolling in clover and nibbling grass to freshen his breath. He picks a yellow dandelion as a gift.

Chapters 1-10 Analysis

This section establishes Isaiah’s character and the stakes of his situation. The narrative begins in medias res, or in the middle of the story, thrusting the reader into the action as Isaiah and his siblings attempt to escape from a place described only in vague, ominous terms—“foul and creepy and 100 percent HORRIBLE” (1). This heightens the tension and stakes. The authors also establish Isaiah’s character and the arc he will have to undergo in The Journey of Self-Discovery. Isaiah is the youngest and smallest of 97 siblings and describes himself as the most cowardly. He speaks to the reader in what is known as direct address, fully conveying his fear and confusion when separated from his family. This reveals his vulnerability and invites the reader to connect with him. It also establishes a baseline for his later growth. Despite Isaiah’s fear, his actions demonstrate an underlying bravery that he is not ready to acknowledge.

The antagonists, Mr. Brophy and Dr. Ledbetter, are established, though not by name. The snarling one is the professor who criticizes the janitor for leaving the laboratory door open; this detail will become important during the story’s climax.

The opening chapters focus on Isaiah’s tense solo escape from the lab, but the authors infuse a playful tone through Isaiah’s humorous, self-aware commentary. This provides moments of levity that balance the book’s heavier themes. Sutphin also intersperses the book with illustrations of narrative events. While most depict isolated events from the story, a few are used to advance character development. For example, Isaiah’s illustrated confrontation with the rats and Lucifer shows his bravery. By shouting human words at the rats, Isaiah demonstrates his cleverness and self-reliance. It’s his first true act of courage, signaling a shift from being the “coward” of his family to someone capable of defending himself.

Additionally, Isaiah’s tactical response to Lucifer’s attack—curling into a ball and counterattacking—illustrates his cleverness and ability to adapt. His choice to fight back physically by biting the cat’s ankle contrasts with his earlier reliance on his voice. He decides he will no longer be a passive victim, and rejects the role imposed upon him by his circumstances. This echoes a key theme of the book, The Importance of Embracing Individuality. In daring to act, Isaiah both thrives and survives.

Some characters depicted as antagonists, namely Lucifer, are characterized by their uncommon looks. Sphynx cats are often portrayed as villainous in fiction due to their “strange” hairless appearance. Although Word of Mouse generally celebrates the uniqueness of individuals, having a cat with a non-standard appearance as the villain contrasts with the message that differences should be honored.

The book makes biblical allusions. The cat is named Lucifer, after Satan, while the protagonist is named Isaiah, a biblical prophet. The quotes from Isaiah that begin most chapters have a proverbial style. For example, Chapter 2 opens with: “God gave us the acorns, but He doesn’t crack them open for us” (6).

These opening chapters also focus on Isaiah’s longing for comfort and familiarity. This is shown when he follows the scent of apple pie into one of the suburban houses. However, the aggressive reaction of the woman baking is a reminder that society perceives mice as pests. The incident deepens Isaiah’s isolation in this new and alien setting. The authors focus on his physical exhaustion and loneliness, an invitation for reader empathy. However, they do not keep him physically isolated for long. The section closes with him hearing another mouse singing, reminding him of his long-lost mother’s singing. Isaiah’s determination to find the source of the song showcases his deep-seated need for connection. This signifies a turning point in the narrative, where hope and the potential for companionship re-enter Isaiah’s world.
