What is the author's style in Ender's Shadow by Orson Scott Card?

A few terms are borrowed from modern street slang, such as "crew" for a type of social structure not formed from blood ties. Achilles turns the slang to the familiar term "family," which in modern usage has a negative connotation within certain contexts involving manipulation and murder. His purpose is to knock Poke off her leadership role in her crew and possibly to build a growing crew of his own with stronger ties to him. His murder of Poke suggests the negative connotation of family, as does his history of being a serial killer.
