Changing the Past

Stephen King’s long read, 11/22/63, is the writer at his best--and worst. Part-alternative history, part-fantasy, this is the story of one man's attempt to travel back in time to stop the Kennedy assassination. The provocative idea of time travel and changing the past, utilizing the string theory, is intriguing. The research layered into the story rich in details is fascinating. The characters are each fully developed as is the story line. However, in my opinion, the 750-page book goes on far longer than necessary. 

Winner of the 2012 Los Angeles Times Book Prize, 11/22/63 was definitely worth the read.
