When I was a Junior in high school, I asked my mother what her favorite book was. She told me that it was The Forsyte Saga. I read the book at that point to feel a connection with her and enjoyed it. I have read the whole saga again several times and still love these novels.
The books may seem slow to you and a bit old fashioned as you start but I highly recommend giving them a chance. The characters come to life, the relationships are well described and a period of English life is well portrayed. Among the memorable characters is Soames who wishes to not just marry, but to possess, Irene. There is Bossiney the architect who has relationships with several characters after he is hired by Soames. There are Jolyons old and young and scores of members of the clan. You will get to know them well. Characters are nuanced, even those whom you may not like, you will come to understand.
The books have been made into TV series twice. In one there were 26 episodes, I think. More recently, in fewer episodes, the series starred Damian Lewis as Soames. This version is on Amazon Prime. However, try reading before watching…please.
