What is the author's style in Oryx and Crake by Margaret Atwood?

Atwood writes in casual language, including many fragments and run-ons. This casual use of English helps create a realistic character who thinks in genuine human speech patterns. Atwood tells the story from Jimmy's cache of memories, creating a voice for the character that highlights his sarcasm and love of vocabulary. He frequently reminds himself of words that he once used when he had people to talk with - sere, for instance, and incarnadine. Sometimes he remembers the words but not the meanings.
