Gryphon Reading List

Hello! Welcome to the Gryphon List. This is a list of all of the books that prominently feature gryphons in them. If I’m missing one, use the contact form to let me know. I’m working on…

@kvalenagle wow, I'm glad you included Meredith Ann Pierce's Firebringer Trilogy! I love those books! But hardly anyone has heard of them...

@lalah The paperback covers for that series went pretty hard! And a lot of people recommended them to me, so I think the series has at least a few fans =)

(The list began because I set a challenge to read 100 gryphon books in a single year, and a lot of people offered up suggestions, so I put them in a list. Over the years since then, I've updated it as I learn about more gryphon books. Honestly, there were so many books I didn't get to in the initial challenge — plus some like Firebringer where I only got to read the first — that I've been tempted to do a new challenge.)

@kvalenagle I'd definitely recommend reading the whole trilogy! The gryphons get more developed as the story goes on. There's actually a unicorn/gryphon romance between minor characters in book 3.
