Well, I'm not surprised with the end cause I've  read "what have I done short series before this and got interested pretty much to know out the whole story. Still there's one thing that seems to me strange. But previously I would say that I writeI all this not to dissapoint you or to criticize you writing with malicious intent but to let you know once again what I think of the story.
So the moment that disturbs me is why Martika wasn't caught by guard immediately as soon as she made her attempts to deliver to Loki the letter. The circumstance that the king was trying to investigate the treason plot for three months without getting any success in that deal gives to me an opportunity to think that if someone tried to give to him some anonymous letter right on the day of execution that fact would be strongly suspicious and the closest guard of the royal person would surely know what to do.
So that's my wonder of moment in the story that seems to me a little bit weak. And I just aught to say now once more that I love the whole your Loki's universe that you develop in your stories and your writing!
