Peter the Magnificent and Caspian the Super Fine http://mistful.livejournal.com/115137.html Very broad parody of the recent movie of Prince Caspian. Favourite line: LUCY: Does nobody understand? He was played by James McAvoy! PG rating for sexual innuendo and swearwords.
Children they Remain by Tex110 http://www.fanfiction.net/s/2782810/1/ Lighthearted short fic with Pevensie brothers being children in Narnia. Suitable for all.
I hope you enjoy these recommendations and please feel free to post your own. Tell us why you enjoy the fic, where to find it and warn for ratings and slash/het.
