After a great storm runs amok in Ponyville all attention is focused towards rebuilding. The CMC help clean up the library with their class. As part of school every student checks out a history book for a report. However in Ponyville's library not all books are as harmless as they seem. From love potions, cloning mirror pools, to prisons for ancient evil these books can cause serious damage and the CMC take one of these home. Turning it into a sleepover that none of them will ever forget for the rest of their lives.
