Obsession is the continuing saga of Captain Evan Knight and the former Mrs. Kate Rivers, now his wife, as they seek to bring both physical healing and spiritual deliverance to some of the darkest corners of Honduras through The Good Ship program. Having seen some of the marvelous things that Kate accomplished in Jesus's name, a second member of the same Caribbean family attempts to attain what he sees as her powers by abducting her. An earthquake, a devastating tsunami and the hijacking of the Good Ship are all things they must face as Evan works to rescue his pregnant bride.
