Homer wants to prove Lisa wrong, by saying how he could write a better children's fantasy book than her. Therefore, he makes a team consisting of himself Bart, Patty, Moe, Principal Skinner, Professor Frink and Neil Gaiman. Meanwhile, Lisa has plans for a single made novel, but she just can't think of an idea and Homer ends up making her the fake author of the teams' book.
Homer and Marge take Maggie, Bart, and Lisa to Dino Land. After the show, Lisa sees a costumed dinosaur, and follows it backstage. Lisa recognizes the actor as the writer of the Angelica Button book series. However, joy turns to shock when she reveals that she did not in fact write the book. Instead, she just posed for the cover, and a tired team of underpaid authors wrote the book. A dismayed Lisa tells Homer what happened, and Homer is interested in the idea of writing a children's book. He enlists Bart, Patty, Moe, Seymour, and Professor Frink to help write the book. However, Lisa thinks she could do better, and decides to write her own book. At the library, Homer and the gang decide to write a book about trolls. Suddenly, Neil Gaiman appears, and offers to help write the book. The crew begins to work on the book, while Lisa dawdles with her own project.
