Query: This series,

Jane Feathers' The Emerald Swan, gives just cause why stories should not come in sets of 2, 3, for more books as a rule. They lose their luster! The first books in this series was enjoyable but it lost it for me after that. The last books were boring and predictable. What's with all the romance novels being sold into so many books on the same story line anyway? I hate that. When I read a story and buy a book I want an ending and I want it to end with each book, thank you very much! I will not be reading any more romance type series books ever again. Yes, I am that annoyed!
