I have hundreds of leaves but no roots or branches. I have a spine but no bones. Open me and worlds appear. Close me and they vanish. What am I?

Question

Accepted Answer

A Book. A book's leaves are its pages and its spine is the bound edge — neither are real leaves or bones. Open a book and entire worlds come to life through your imagination.
