I can't really sum this one up in a couple of paragraphs, but I'll do my best. Basically, it's the story of a son's attachment to his mother and how this stops him from forming a successful relationship with women. Mrs Morel's love for her son Paul almost smothers him to the point of suffocation and gives him a sort of emotional handicap, as he's constantly searching for his mother's approval in all that he does. His first relationship with Miriam doesn't work out, because his mother doesn't like her. His second relationship with Clara fails because Mrs Morel is ill and he can't concentrate on anything else apart from her. OK, so this could just be the story of a standard mummy's boy who takes it a little bit too far, but it's a little bit more sinister and twisted than that. At one point, Paul takes his family on holiday to the seaside and goes for walks with his mother, treating her jealously if she pays attention to others, and treating her almost like a lover. Nothing is said explicitly that anything dodgy or incestuous is going on, and I'm not sure that there was, but there are certain undertones of a deeper sort of love that Paul feels for his mother.
Paul's only meaningful relationships are with his family and women, so it's interesting to see how he behaves with men; he only really gains male friends about 100 pages from the end. The contrast between the two types of relationships is clear. With the men, Paul is coarse and base, but with the women he allows himself to think more and to become more philosophical.
The whole book is a journey of not-quite-realisation for Paul, as he never really learns how to correct his ways and thereby move forward. We see him make the same mistakes over and over again and see his unavoidable demise throughout the book. It's definitely worth a punt, because it's genuinely fascinating and well-written (it's partly autobiographical, which gives some insight into D.H. Lawrence himself) and really beautiful. Next on my list is Women In Love, by D.H. Lawrence again, to see if Sons And Lovers was just a one-off hit! I'll keep you posted!
