The listing is for book #22 from the Horus Heresy series:
Shadows of Treachery

The book has damage to the spine (see separate image), so should be considered a reading copy. Covers and corners have wear as well, pages are yellowed. Keep this in mind when considering a purchase.

I can usually ship items Mon-Wed, but in 2024 that's only Dec 23 and Dec 30. I use Omniva (Estonia Post) to send packages.
