As I presume will be the case with many people I came to the novel of Wild at Heart being already familiar with David Lynch film version, which turns out to have been a fairly faithful adaptation. Much of the quotable dialogue from the novel survived the transition from page to screen, and aside from Lynch's additional 'feel-good' ending most of the differences are a tightening of the backstory (the whole connection between Sailor, Lula's mother and dead father is absent here) and a hyping up of the darker elements (the novels Bobby Peru is noticeably less intense than the movie version, while Marcelo Santos and the dire fate of Johnny Faragut are nowhere to be found). While 'Wild At Heart' as a novel is incredibly short on actual plot what it does boast is some tremendously vivid characters, with most of the novel consisting of small vignettes of characters telling stories to each other on the road.
A short but vivid, and very readable novel.
