From award-winning author Matt Cost comes a thrilling mystery about Unexplained Aerial Phenomena (UAP) spotted in the skies over Port Essex, Maine.

The man—about forty, forearms like small oak trees, with a thick beard—told the bartender at the Pelican Perch, "It came right up out of the ocean, hovered just above the water for about ten seconds, and then was gone."

When Clay Wolfe and Baylee Baker are hired as the local liaisons for a government task force investigating the recent UAP sightings, things get complicated at lightspeed.

They're also hired to find the missing Alice Smith, whose disappearance increasingly appears to have something to do with the UAPs—the source of which might just be a governmental defense contractor named Seagull Aviation.

But the more they investigate, the more questions pop up. Who is the assassin gunning for Wolfe and Baker? Who is the mysterious man code-named Arrow? When each witness who has seen one of the UAPs is reported missing, the stakes become sky-high.
