Great, enchanting, keeps you wanting more! All of Galsworthy's stories about the Forsyte Family are like this.
I read these books when I was about eighteen in 1962 and was taken back to them when the BBC did the first Forsyte Saga series with Eric Porter as Soames and Nyree Dawn Porter as Irene, in late 60's early 70's. This was an excellent adaptation - the later one, made in about 2002 is awful in comparison (see my review on this). Nyree Dawn Porter will always be Irene to me, as Eric Porter will always be Soames.
They are not 'dated' as you might expect, as the intrigue, love, passion and greed are there just as much as in any racey novel of today, albeit, perhaps not in so many words..., nevertheless it is so well written that you get the gist just the same.
The scope of these stories is immense, taking in the Forsytes, their many relations, friends and acquaintances, all living, breathing, fighting and loving in these wonderful books.
Do read them, if you can - when I bought them in about 1964 they were in three volumes and are now available as separate books and in an omnibus edition, I believe. They are well worth whatever you pay, believe me and I know you will love them as much as I do.
