Everlasting Honor is not a book per se, it is basically an extension of the epilogue started in Royal Honor. Honor is heavily pregnant with their first child and finally claimed her throne. As an assassination attempt was prevented, Honor and her men start looking for the ones responsible. Meanwhile Honor gets some time with each of her men alone (and also together) while breaking the scourge stone and going off into the world revisiting some of the important settings of the former books, but also new ones, in order to hide the pieces of the stones. Their kingdom needs to be perfect for the arrival of their little dragon. While her men are already planning to make more babies, Honor makes some diplomatic connections with foreign princes, basically introducing the spin-off series that will concentrate on her sister Hanna's story. Everlasting Honor is a nice conclusion of Honor's story, giving us a nice and romantic way to part with the series.
