A verse novel is a long narrative work that tells a story through poems rather than prose. It usually follows the shape of a novel, with characters, scenes, and a developing plot, but its language is broken into lines and stanzas, allowing rhythm, compression, and lyric feeling to carry the storytelling.
Example
By midnight, Nora packed the keys in her coat pocket,
left the lamp on, and watched the kitchen glow thin and small.
At dawn she was already three towns away,
with one suitcase, one apology,
and a letter she never mailed.
