A dead man left her a map of the sky. Now someone wants her buried beneath it.
When federal agent Ava Martinez receives two cryptic will from a dead uncle—a blurred map fragment, mismatched metadata, and coordinates pointing deep into New Mexico—she knows one thing: someone wanted this message to reach her, and someone else tried to hide it.
Ava is supposed to be on her way back to D.C., closing out her temporary life in Florida. Her Siberian Husky, Atka, is already there with a trusted handler. But the moment she sees the map’s timestamp—three weeks before Miguel Serrano’s death—she changes course. Two devices. Two senders. One attorney who shouldn’t be able to email anyone.
What waits in the desert is not a simple inheritance dispute. It’s a network of secrets tied to land rights, old betrayals, and a conspiracy that has been quietly shaping the Southwest for decades. As Ava follows the coordinates through balloon fields, arroyos, and abandoned parcels of land, she realizes Serrano didn’t leave her a clue.
He left her a warning.
Someone in New Mexico knows her federal identification number. Someone knows she’s coming. And someone is willing to kill to keep the sky—and what’s hidden beneath it—from being found.
Altitude Drift is a tense, atmospheric thriller perfect for fans of Michael Connelly, John Grisham, and C.J. Box—a story of maps, secrets, and the cost of uncovering the truth in a landscape that keeps its silence well.
