Christ, this fic is good. Merlin pisses off a nobleman and accepts a fight he'll never win, Arthur comes to realise as he tries to prevent the fight from happening that he really cares for Merlin, Merlin reveals his powers, Arthur accepts them, sex ensues, and everyone lives happily ever after. It's typical, but it's by no means boring.
Not gonna lie, the beginning is somewhat messy. I almost stopped reading, but I pushed through the first few untidy paragraphs because something about the author's voice ("I am a prince. I have *servants* to build bridges if I want a bridge!" "Of course, Your Highness. Please examine your figures here; perhaps you did not mean for your bridge to collapse into the river?" -- mind you, the asterisks are going to annoy the hell out of you all the way to the end of the fic) caught my interest. I'm so glad I did, because the writing cleaned up quickly and the rest of the fic was a smooth, enjoyable read.
The best part of the fic is undoubtedly the UST. There's none of that contrived "their fingers brushed and both of them jerked their hands away, blushing" nonsense. The UST build-up in this fic is so natural that I never once felt the urge to roll my eyes at how obvious the author's efforts were. There's one scene where Arthur applies a salve to a wound on Merlin's back that's utterly gorgeous. The same can be said of the undressing scene leading into the sex. Speaking of the sex, OMG. It's perfect. The whole scene is so poetic and beautiful, but incredibly real and not at all purple prosey at the same time. I felt like I was reading slash for the first time all over again. Seriously, any fic that can make me feel that way is worth giving a shot. Go read it! :D
