I starting participating in Birthstone Books Covers in August 2025, and I’ve stuck with it ever since. I’m now in my 2nd time through, so the challenge is to find new books to spotlight! Leslie at Books Are the New Black hosts this fun monthly meme — why not give it a try?

The rules are simple:

Mention the creator (Leslie @ Books Are The New Black ) and link back so she can see your post! Pick 5+ book covers that match the current month’s Birthstone. HAVE FUN!

September’s birthstone is sapphire. According to the American Gem Society, sapphire gemstones symbolize loyalty, nobility, sincerity, and integrity. Learn more about their history. 

Sapphire is my birthstone (yay, September!), and I’ve always loved the rich color (and love checking out sapphire jewelry of all sorts). But more importantly…

Onward to the books! What a dilemma I’m facing — I featured a bunch of absolute favorites last September, and I promised myself I wouldn’t do repeats this time around!

So, here are more sapphire book covers I’ve found on my shelves… and if you’re curious, here are the sapphire books I featured in September 2025!

• The Glory by Herman Wouk
• A Deadly Inheritance by Kelley Armstrong
• Meat Cute by Gail Carriger
• The Christmas Book Hunt by Jenny Colgan
• Bellewether by Susanna Kearsley
• The Calculating Stars by Mary Robinette Kowal
• Night Road by Kristin Hannah

Do you have any favorite sapphire book covers to share?
