I read an article today in the Journal of Cultural Equinology and Magic about a new book club called the Panequestrian Haycartes Society. It's not at all what I thought it was. This book club doesn't discuss books, they get books to interact! Somepony has found a way to expand Moondancer's Haycartes variant to include not only other editions of the same book, but other unrelated books simultaneously. Initially it was supposed to be an academic tool to aid in cross referencing books for research purposes, but a group of students seized on this as a way to create a Ffjordian bookverse and apparently this new book network has become quite popular. The article appends a thorough description of the spell and how to cast it. I'm a bit leery of variants on Haycartes after that time I got trapped in a corrupted enchanted book but this sounds tempting. I'm going to give it a try tomorrow.
