Series Premise

The Grey Griffins series follows four friends—Max Sumner, Harley Eisenstein, Natalia Romanov, and Ernie Tweeny—who form a secret club after ordinary playing cards filled with mythical creatures begin manifesting in their world. They battle an escalating threat of dark magic, goblins, faeries, and powerful ancient orders while uncovering their own emerging abilities and roles in a hidden conflict between good and evil.

The Grey Griffins Series Reading Order

Readers who skip ahead will miss the natural progression of the friends’ teamwork, individual power discoveries, and deepening stakes that make later events more meaningful.
