I really appreciate the idea that inspired this poem and the imagery of a single book sitting, lonely on a shelf, waiting to share its message, its story, with even a single reader.

The second verse is STRONG: Fantastic imagery and clear communication about where said book will come to life and be heard:
I am silent (if nothing else).
I only speak when opened,
And then softly, in a hush, heard
behind the eyes, between the ears.

Suggestions:
1. I did, however, and this may be only one person's opinion, fall off when the book pleaded with me to read it. Its cry became a plea for attention. I would rather it be more empowered and tell me what I am missing if I do not let "her" speak. IDK, maybe something like:

If you could hear me now?
My gist, I would share so proud.
Images and schemes would surely dance
If you would give to me this chance

2. You could get more exposure by adding more genres. I think this would fit nicely in the writing genre, and dare I say even the romance genre. YES! I dare say. There are many forms of romance and when we fall in love with a book . . . Well, you get my drift.

Correction:
1. Hardwood is either one word or if you meant it as hard, wood plank then you would need to add a comma. That said, my husband said it works as is for him. But I had to read it twice and still wasn't sure which meaning you were intending.

Again, I absolutely love the idea behind this, and if I may, one final suggestion: I think you could do a series of poems on the same subject.
Possible titles: Ink in Isolation, Pages in Solitude, Protagonist on a Shelf.

Live and write passionately,
Cyndee
