The day starts out like any other, until Sunny Starscout purchases a most peculiar book. She brings it back to her friends for a little book club, until the book itself transports them to the land of Middle-Earth. There, they become involved and a part of the Company of Thorin Oakenshield, and by extension alongside Bilbo Baggins. Along the way, they encounter a plentiful of beings and creatures such as Elves, Hobbits, Dwarves, wizards, and a Skin-Changer; but also the Orcs of Gundabad, the Goblins of the Misty Mountains, and the great Fire-Worm that stole Erebor all those decades ago.

Not only with the Mane 5 risk their own lives and their friendships, but also discover more about themselves.

LOTR tag because it's set in Middle-Earth.
