Final answer:
A "brown out" refers to a disruption in electricity and cell towers caused by a decrease in voltage. While a specific book is not mentioned, disturbances in the electrical grid due to natural events can be found in works of fiction.
Step-by-step explanation:
A "brown out" refers to a disruption in electricity supply that causes a decrease in voltage, resulting in dim lights or flickering lightbulbs. It can also affect the functionality of cell towers, leading to a loss of cell phone service. While I couldn't find a specific book mentioned in the question that includes a brown out, disturbances in the electrical grid and communication systems due to natural events like solar storms have been depicted in various works of fiction, such as "One Second After" by William R. Forstchen. These events add tension to the narrative and explore the consequences of a power outage on society.
