covers

[jellytea]

So I was looking through my favorites of various Sheldon/Penny fanfiction and drabbles and I thought I had favorited a post that had covers of stories and then when you click on the covers, it led to a PDF of the stories that community writers had written.
BUTTTT alas I favorited the wrong one. Does anyone know what I'm talking about?
Can someone help me find the linkage? =D
