Query: The Fifth Horseman

I have been a huge fan for a number of years. Consider my delight when I finally found an established male author willing to take on female heorines. However this series is totally lacking in plot concept and character development. In The Fifth Horseman, I knew the ending in the first 1/4 of the book. The remainder was real yawn. I couldn't even find anyone to empathise with. This is the first hardback I'm seriously considering throwing away. Not even good enough for good-will.
