When starting a book , the story is not always clear , but Connelly has a hunch where it is going . The books often reference world events , such as the 1992 Los Angeles riots and the September 11 attacks . Even events that might not be considered as world-changing are included in some of the books , because they are of personal interest to Connelly . For example , in '' City of Bones '' , Detective Bosch investigates the murder of an 11-year-old boy . This was written during Connelly 's early years as a father of a daughter , and it hit close to home . According to Connelly , he did n't mean to write about the biggest fear of his life ; it just came out that way
