Luisa Rey

In Cloud Atlas, Luisa Rey appears as a young journalist investigating corruption at a company operating a nuclear power plant in California in 1975. She meets Rufus Sixsmith in an elevator, where she is told about potential safety problems at the nuclear plant. Mr. Sixsmith is the recipient of the letters written by Robert Frobisher that form another one of the six stories in Cloud Atlas.

Luisa Rey also appears in Utopia Avenue as girlfriend and later wife of Elf Holloway. They meet at a party in England and then again in New York, although Luisa is delayed due to danger involving her career as an investigative reporter.
