Storm Damage (Cliff St. James) by Ed Kovacs

After hurricane Katrina hit New Orleans people were left homeless, a city was wrecked and crime was at an all-time high. Post-Katrina is the world where Cliff St. James, ex-cop and martial arts expert operates in. Hired to find out who killed a Vietnamese lady's father he confronts the FBI, CIA and several criminals.
St. James is a cool character. He enjoys fancy coffee, cigarillo's and martial arts. He's scarred by his divorce but tries to love women again. Luckily there's a great woman to help him out a bit, awesome lady cop Honey Baybee (really!) who I personally fell in love with immediately.
Ed makes good use of the New Orleans setting, serves up anything fans of PI fiction OR Lee Child style thrillers could want.
