I shan't bother you with a synopsis, other than to say it's probably the best coming of age slash road novel you're ever likely to come across. Since finishing it I took a look at the movie trailer (yep, it got the motion picture treatment back in 2017) and I think I may have to watch it (I know, I know, I'm breaking one of literary's cardinal rules). But I think I may be forgiven just this once: Steve Buscemi's in it. How can I not watch it? Of course it won't be as good as the book, but, did I tell you, Steve Buscemi's in it!
