Keys in the Ignition: The Unsolved Case of Phoenix Coldon is a gripping true crime narrative that delves into the mysterious disappearance of 23-year-old Phoenix Coldon, a talented young woman whose life was abruptly cut short on December 18, 2011. Last seen leaving her family home in Spanish Lake, Missouri, Phoenix's black 1998 Chevy Blazer was discovered hours later in East St. Louis, Illinois, abandoned with the keys still in the ignition and her personal belongings inside. Despite the immediate discovery of her vehicle, Phoenix was never seen again, and the case remains unsolved.

The book examines the investigation's shortcomings, highlighting the lack of urgency and transparency from local authorities. Phoenix's parents, Goldia and Lawrence Coldon, faced numerous obstacles, including delayed notifications about their daughter's vehicle and insufficient media coverage, which they believe was influenced by racial biases. Their relentless pursuit of answers led them to hire private investigators, uncovering startling revelations about Phoenix's secret life, including multiple birth certificates and a hidden romantic relationship. These discoveries suggest that Phoenix may have been leading a double life, adding complexity to the case.

Through extensive research and interviews, Keys in the Ignition explores various theories surrounding Phoenix's disappearance, from the possibility of her running away to the tragic scenario of human trafficking. The narrative also touches on broader issues such as the media's treatment of missing persons cases involving people of color and the challenges faced by families seeking justice. This book serves as a poignant reminder of the unresolved mysteries that continue to haunt families and communities, urging readers to reflect on the importance of attention, empathy, and action in the face of such tragedies.
