When Twilight loses her favorite book, she begins to flip out. Alas, all her friends are out of town, so the only person she has to help her find it is Spike. Maybe they can find it, but if not, she doesn't know what she'll do because after all, that was one of the books Shining gifted her on her birthday the week before she moved to Canterlot, so it means a whole lot to her.
