I really love this T.
Great sounds, wonderful internal rhymes, both full and near. The opening line is a grabber and a half, wow!
A couple sticky spots:
I think you should, or at least could, drop lines 5 & 6:
I would see these trees as firewood
kindling dragged and heaped
at the feet of each new Joan
for the final conflagration-
just feels more potent. This creates a problem of how to lead into S2, which has some just amazing writing. I don't know how to fix it. I like the image of a "second bookend", but those lines feel like pure setup. Even with these functionary (in my opinion) lines in place, it's hard to make the jump to "these books". I have some guesses at them, but I admit to struggling with the books and can only see the "second bookend" as a figurative device and not as a contributing image.
Anyway there is a jump between S1 & S2 that I'm not able to make smoothly. All the difficulty (and I'm well aware it could be with the me as a reader) is in lines 5,6, & 7.
I don't want to overstate the effect.
I also think you could drop the last line of S2. You capitalized the "Book" in line 13. "some would imagine" feels like unnecessary hedging and sonically it deflates the force built up to "Book" That hard stop is huge. When I read it aloud, it literally has the effect of someone saying:
Some say the world will end in fire
or whatever
You may not agree, but I hope I'm being clear in what you'd be disagreeing with.
I spent a lot of time on a couple minor points. I hope the excess of words that appear negative do not overshadow my actual appreciation for the poem. You alway exhibit a great sense of tone. And sonically, most every one of your poems I've read has great movement. This poem is a step above. All the tools are in place and singing so sweetly you have to look for them to know they're there.
You mirrored this tour de force of sound with amazing imagery. I dwelled a bit on S2 because the writing, particularly in that stanza, is so wonderful that even the slightest distraction stands out by contrast.
Finally, I love the way to poem ends. Amazing and on top of that, it's so you you might as well have signed it. Frankly, I don't have a bigger compliment.
Great stuff. Thanks for posting it.
