Pick the title of a book that you love, that title is now the title of the poem. That poem can be about the book directly, or indirectly, or it can use the title as a jumping off point, and be about something else entirely.
Alice in Wonderland-
Alice fell through the hole
to another new world.
A different world it was,
Where life was fun
games were royal
things would grow large or small
All seemed in another age
how wonderful if life would really
be like a book- but books are stranger
than reality-they take the reader
to a dream world,
so let us read and dream
it may come true.
