"The Shondell and Balangie families are enemies in New Iberia's criminal underworld, but teen musicians Johnny Shondell and Isolde Balangie have fallen in love and run away. As Dave Robicheaux investigates the couple's whereabouts, he runs afoul of Isolde's mafioso father, who puts a hit on Robicheaux and his partner, Clete Purcel. The assassin is unlike any they have ever faced: he can induce hallucinations and travels on a ghost ship that materializes without warning. In order to defeat him and rescue Johnny and Isolde, Robicheaux will have to overcome the demons that have tormented him throughout his adult life"--Page 4 of cover.
