Erika Fleur wakes up one morning to find a book on her shelf glowing intensely. The book is a collection of nursery rhymes titled *Mother Goose*, a gift from her grandmother in her childhood that she had long since forgotten. Curious about the light, she opens it and is instantly transported to a grand mansion, where five men greet her as the residents of the book. Along with the mansion’s owner, Mother Goose, they believed they had been forgotten by the world. To help Erika return home, she must now take a series of exams testing her knowledge of nursery rhymes.
