Guests of Honor (Alliance By Marriage, Book 3) - Alliance By Marriage, #3

A wedding invitation is usually a good thing-unless you receive it from your past enemy and find yourself in a position where you can't refuse it. When King Harpax-by now an experienced ruler, a faithful husband, and a somewhat struggling father-has the misfortune of receiving such an invitation, he suspects that things might go wrong. He has no idea, though, what a twisted trap awaits him, and how close he's about to come to losing everyone and everything he loves.
