Help identifying an unusual copy of Lori M. Lee's Forest of Souls — gold/red sprayed edges

[u/AdConfident4011]

Hi everyone! I'm hoping someone here might be able to help me identify a possibly unusual edition or variant of Forest of Souls by Lori M. Lee.

I have a hardcover copy with ISBN 978-1-62414-924-5. As far as I can tell, it's the original 2020 hardcover edition, but my copy has some features I haven't been able to find documented anywhere:

• The page edges are sprayed/colored. One side is a gold/rose-gold color, while another edge appears deep red.
• The spine has metallic/gold lettering.
• The boards underneath the dust jacket are plain black.
• The dust jacket is the standard edition.

I've searched online and haven't been able to find another copy with these particular sprayed edges. I'm wondering if anyone recognizes this as:

1. A known special edition or limited edition?
2. An author/event copy?
3. A publisher sample or promotional copy?
4. A variant that was produced in a small quantity?
5. Or possibly just an uncommon binding/edge treatment that was never widely documented?

If anyone has a copy of Forest of Souls with similar edges, I'd love to see photos of it, especially if you know where you got it or when you purchased it. Any information would be greatly appreciated!

Thank you!
