Inspired by @EtherealPleonasm. This is book of Quatrain Poems, which are all fictional!!! Quatrain: A quatrain is a stanza in a poem that has exactly four lines. Some quatrains comprise entire poems, while others are part of a larger structure. Quatrains usually use some form of rhyme scheme, especially the following forms: AAAA, AABB, ABAB, and ABBA.
