Wildlife photographer Jade Silva's last text message is a photo of a rare jaguar at the US-Mexico border wall.
When Jade vanishes, her fellow Southwestern Research Station volunteer, Sam Westin, agonizes that something terrible has happened. But finding Jade seems an almost impossible mission in a rugged area overrun by undocumented immigrants, Border Patrol agents, vigilantes, construction crews, human traffickers, drug smugglers, and violent cartel thugs. Meanwhile, the ever-increasing militarization of the Arizona-Mexico border is destroying ecosystems and trampling the rights of US citizens. Trying to rescue her friend, Sam is sucked into a maelstrom of desperation, deceit, and danger.
