For January & February we’re featuring P.K. Pages “Improbable Concept,” which appears in the current issue of Poetry Northwest.

The lines of the opening quatrain are chosen from the work of another poet; they are followed by four ten-line stanzas, whose concluding lines are taken consecutively from the quatrain; their sixth and ninth lines rhyming with the borrowed tenth—I suppose a liking for crossword puzzles helps!”
