In 1989, John Sandford published Rules of Prey, about a serial killer who has his own set of rules for selecting victims. It sold well for a first novel and led to the Prey franchise, with a new book coming out almost every year. (The book's titles are chosen by Putnam editor-in-chief Neil Nyren. 'He only has to think of one word, like, you know, 'Naked',' Sandford says.) Naked Prey (ISBN: 0399150439) Davenport is plunged into a mystery in Minnesota. The naked bodies of a black man and a white woman are found hanging from a tree, and it's up to Davenport - now the governor's political 'fixer' - to quell talk of a lynching. The Hanged Man's Song (ISBN: 0399151397) A break from Sandford's Prey series. Well-written, the book is equally, if not more, interesting than Detective Davenport's stories. The book revolves around computer hacker Kidd, who finds out that a super-hacker, whom he has never met but has relied on many times, has been murdered.
