Payback (Anonymous Justice #2)

Former NYC prosecutor Kate Stone has found herself on the wrong side of the law since leaving the district attorney's office. She returns to confront her former boss, D.A. Frank Rubenstein, and discover all he knows about the corruption in NYC law enforcement and the legal system, where rich men are using dark money to gain advantages. She must decide whether the ends justify the means when she accepts Rubenstein's help and the help of his ragtag team of vigilantes to bring down the corrupt men her policeman father was investigating before his mysterious death. And she will finally clear her father's name.
