Twelve-year-old Jolene spends every day she can at the library watching her favorite livestream: The Desert Aviator, where twelve-year-old "Addie Earhart" shares her adventures flying an ultralight plane over the desert. Addie, who is grieving the loss of her father, finds solace in her online conversations with Jolene, her biggest - and only - fan. Then, one day Addie's engine abruptly stops, and Jolene watches as the ultralight plummets to the ground and the video goes dark. Jolene knows Addie won't survive long in the extreme summer desert heat. With no one to turn to for help and armed with only a hand-drawn map and a stolen cell phone, it's up to Jolene to find a way to save the Desert Aviator.
