The sentry
(Book)

Dru Rayne and her uncle are Louisiana refugees who relocated to Los Angeles after Hurricane Katrina. Now, five years after the storm, their struggling restaurant faces a different danger. When Joe Pike witnesses Dru's uncle beaten by a neighborhood gang intent on extorting protection money, he offers his own brand of protection. But neither Dru nor her uncle want his help--and neither do the federal agents mysteriously watching their store.
