Birthstone Book Covers: September 2025

Wow, it’s really late in the month again. Not quite as late as last September, though it’s pretty close.

Leslie @ Books Are the New Black created a fun monthly post called Birthstone Book Covers. Each month, she features book covers that are either the same color of that month’s birthstone or include the color in the title.

September has one birthstone – Sapphire. It’s a blue birthstone month!

Rules:

📚 Mention the creator (Leslie @ Books Are The New Black) and link back to her so she can check out your post.
📚 Pick 5+ book covers that match the current month’s Birthstone.
📚 HAVE FUN!
📚 Nominate people if you want!

A Game of Thrones by George R.R. Martin
The Frugal Wizard’s Handbook for Surviving Medieval England by Brandon Sanderson
Dark Moon, Shallow Sea by David R. Slayton
The False Prince by Jennifer A. Nielsen
The Dreadful Tale of Prosper Redding by Alexandra Bracken
The Bronze Key by Holly Black & Cassandra Clare

What are your favorite books with blue book covers? If you participated in Birthstone Books, which books did you choose this September?

Thanks for reading, and I hope you have the most amazing day/night!

See ya ~Mar

    • Thank you! And yeah, Dark Moon, Shallow Sea’s cover is so pretty and eye-catching – it’s what made me interested in reading it in the first place.
