I Am Wrath (The Ackerman Thrillers): 4

'A fast paced, all-too-real thriller with a villain right out of James Patterson and Criminal Minds' ANDREW GROSS.\nMy wrath knows no bounds. Your torment knows no end.\nAn Arizona prison officer climbs his watchtower and opens fire on the inmates and guards below. Federal investigator Marcus Williams needs to know why. What he unearths is that the prison has become the hunting ground of a psychopath known only as 'Judas'.
To uncover Judas' identity, Williams must join forces with serial killer Francis Ackerman Jr. While Williams works the case from the outside, Ackerman Jr. goes undercover among the prisoners on the inside. What neither of them know is just how diabolically ambitious Judas' master plan is...\nPraise for Ethan Cross:\n'Francis Ackerman [is] a manipulative monster with a corrupt conscience' THE TIMES.
