Anna Weaver has spent eleven years working the forests of the Ozarks. She believes in what she can see, measure, and document?until the day the forest stops behaving like a forest.

Dead birds begin appearing without cause. The air turns still. The silence deepens. And somewhere in the backcountry, something feels... wrong.

When Anna follows that wrongness off the trail, she finds herself stepping through a thin place in reality?into the Between, a hidden layer of existence where the boundaries between worlds are breaking down.

There, she meets those who walk the margins:

• A man who has been waiting for something he cannot stop
• A pathfinder who exists half in and half out of reality
• A trickster who may be ally, enemy... or both

And beneath it all, something older than myth is stirring.

A force known only as the Devourer?a hunger that cannot take what is not given, but waits patiently for the moment when people choose to surrender.

As the walls between worlds weaken, the corruption begins to spread?not just in the Between, but back in Anna's world as well.

Now, she must decide:
Walk away and return to the life she understands...
or step fully into a war she was never meant to fight.

Because some doors don't just open.

They remember who walked through them.
