You want Crystal Sprite's 'How I spent my Summer Vacation' which can be found over at Crystal's Storysite, I think. This is one I asked about around a month ago, you might still find the blog which had a link in it in the archive here. I think it was around the end of June or the beginning of July. The story is a really great read and worth the effort to find!

For the Robin story, I'm not so sure but have you tried Zoe Taylor's 'Becoming Robin' series?
