Hated the ending of a book

Ok ok I am lover of books sometimes I complain about the ends of movies, I haven't read a book where I wanted to yell at the book after I read it. Yes it is true I hated the ending of this book it was stupid sorry for those who loved it.  An Ember In The Ashes is a great read until the end. The book takes place in a wold like Rome where where there is a strong female lead shared by a strong male lead that are star crossed lovers that never really got a chance to be together or so we will never know. The book end so aruptly that we do not know if the main characters die or live ... Also we do not know if there will be a second book at this time to finish the story off. I feel as tho this book started a story and I read it for no reason as I never got an ending. The writing is great the plot is awesome but I want to know the ending to the story.
