The last time I saw my sister Emily, she was holding a crumpled road map upside down and laughing so hard she had tears in her eyes.

“Abby, you should see this thing,” she said, shaking the map at me. “Jack insists this is the right way, but I think we’re already lost before we even leave the driveway.”

Jack Sullivan, her boyfriend of three years, leaned out the window of their old Jeep and grinned. “She has no faith in me. We’ll be fine. It’s a straight shot down I-84.”

It was a Friday morning in May of 2011, and the air in Boise smelled like cut grass and adventure. They were headed to a remote stretch of the Nevada desert near Winnemucca, planning to camp for three days, take photographs, hike, and be back by Sunday evening. Just a simple weekend getaway for two people in love.
