Annoying book

I am having difficulty finishing a historical novel. Not even that it is badly written, the style is good and I have read books by this writer before and liked them. But I am not enjoying child of the phoenix by Barbara Erskine. The plot is sooooo ridiculous that I have to force myself to keep reading. It centers around Ellen, the daughter of Llewelyn the great. I have stated before that her parents are badly depicted and I disliked that already. But the plot!!!! Ellen married twice, first to the earl of Chester, a man she did not marry, second with Robert de Quincy, a poor knight, the second was a marriage of love that lasted untill her death. In this book they have de Quincy die before her, besides he is depicted as a monster and it is not a happy marriage. And then she has an affair with the kind of Scotland and is later abducted and forced to marry another scottish nobleman. It is absurd!!!! I mean if you want to write nonsense, just invent characters and then you can do what you want. Ah well I always finish my books so I am going to finish this one.
