She became a wolf to survive.

Rowan is a Watcher, a protector of Elderglen and guardian of its borders, the last line of defense against what lurks in the woods. When grief left her hollow, she begged the forest goddess Rhiann to make her wolfkind: faster, stronger, wilder.

But now something dark hunts those she's sworn to protect.

Some are found drained of blood, others frozen in terror, and Rowan worries she isn't strong enough to protect those she loves. When her grandmother dies, Rowan becomes the Cornerstone of Feather and Claw, a secret network whose sole purpose is to destroy a murderous cult targeting anyone with magic.

Another title to bear, another weight to carry.

With a stranger at her door and traitors within, Rowan must untangle the lies before everything burns. She's sworn to protect Elderglen, but the forest is calling her deeper, and wilder, than ever before.

Watcher. Guardian. Cornerstone.

But all she wants to do is run.

Wild things deserve to thrive.

Filled with feminine rage and wild hope, leap into the fourth adventure in The Dark Library Series, where tempers burn and grudges simmer.
