I wrote the poems in Charms Against Lightning one by one, over almost a decade, and I did not write them toward any theme or narrative. But once I really got serious about putting together a book, I began to see that in fact there were themes across the poems, if only because my own obsessions had brought me back time and again to the same ground. I realized that any ordering of the poems would determine how those themes developed over the manuscript, and how the collection's dramatic conflicts were resolved.
