I am glad you like the later books.
I enjoyed them, I thought they were good, and im never good at judging quality vs just whether I like a book or not.
It is just that the books took the characters and setting in a direction I didn't like, which happens, happens in many different series whether books or TV or movies.
But when something like Destinies comes along, gives me something to latch on to say that the books I didnt like are in an alternative timeline now, and now the new timeline may go in a direction I do like. A pure emotional response, but it is there nonetheless.
