Narnia Fic Challenge

I really like how Peter trusts Lucy implicitly but has to learn to extend that same trust and faith to Susan, because yeah, they all love and need each other, but love doesn't make everything work smoothly on its own. Tangentially, I like that this is a story about Peter and his sisters, and secondarily about Lucy-and-Susan, with Edmund hanging unobtrusively about in the background instead of everything being Brotherly! Devotion! Forever! (Not that there is anything wrong with brotherly devotion, but there are other stories, you know? Well, of course you know. You've told one!)
