This fall’s novels to watch for

This fall’s must-read fiction includes novels set in China, India, London, San Francisco and New York; two exciting debuts by Australian writers; stories from authors who’ve received the Nobel Prize, the Pulitzer and more; hotly anticipated titles from book-club favorites including Jhumpa Lahiri, Elizabeth Gilbert and Wally Lamb; triumphant returns from reclusive legends Donna Tartt and Thomas Pynchon; stories of revolutions both political and scientific; hilarious novels about misfired relationships and tomes that grapple with the meaning of life in the past and present.
