"Even if you’re totally unfamiliar with the Easter story, this short reading list should more or less work for you. It’s all actual biblical text, abridged and slightly rearranged to make the narrative easier to follow. It doesn’t include every detail; read each of the four gospel accounts separately for that (like you should! ha)."
This post links to a number of documents with Easter-related reading content. As the author says, reading about something you are already quite familiar with is definitely easier than reading something completely new!
