This series started out so well but I think 6 books was a stretch.  In this last book there were chapters where nothing happens outside of the FMC or one of her bonds talk about how much they love each other and how much they've changed since they first met.  

The author has introduced so many new characters but just drops them as soon as they've served their purpose.  

I know that some readers don't like the epilogues of years down the road with kids and silly interactions but this whole book was a bit of a let down.
