A vanished sheriff. A forgotten clearing that shouldn't exist. And a bloodline pact older than the town itself. Copperwood doesn't show up on most maps, and that's exactly how the people who fled there like it. Wedged against the Canadian border, it's a dying mining town full of hard people running from harder pasts. So when its longtime sheriff walks into the woods and simply disappears, nobody expects the truth to be anything but tragic. Spencer Cole isn't looking to be anyone's hero. A former Marine sergeant chewing through whiskey and nightmares from an ambush in Herat he still can't explain, he's spent years chasing the unexplainable - the claw marks, the sigils, the things that don't fit in any official report. So when an old friend and fellow veteran, now a Maine county sheriff, begs him to take the vacant badge in Copperwood, Spencer knows it's not really about law enforcement. It's about what's hunting in those woods. What he finds is worse than he imagined. A Wabanaki elder who swears the end of the world has already begun. A copper-mining dynasty, the Van Hornes, hiding a four-century-old bargain struck to protect the town and the land. A hidden clearing that appeared out of nowhere, exactly where the old sheriff vanished. And a secretive organization called The Odd World Society, whose reach extends far beyond one small town. As disappearances mount and the veil between worlds grows thinner, Spencer must decide how far he's willing to go to stop something ancient from finishing what it started, before Copperwood - and everyone in it - pays the price for breaking a promise made generations ago.
