What is the author's style in How I Live Now by Meg Rosoff?

Probably the most notable characteristic of the writing in this novel is Daisy's penchant to capitalize Important Phrases. She does this frequently for comic effect and it beautifully showcases both her dramatic flair and her ability to put her finger on the pulse of an issue or situation. The other key aspect of her narration is a tendency to string together long sentences, made of phrases that meander from one topic to the next, as if she were simply recording the course her mind happens to be taking, until her thoughts return at last to their starting point with a conclusion that manages to unite all these seemingly independent phrases. As the story goes along, she starts using less teenage slang and larger words, even while events in the novel become increasingly darker. The section at the end indicates that six years have passed, and Daisy, now 21, narrates the story in a more adult-sounding voice than her catty and affronted tone early in the book.
