"Latent Image" by Wesley Long is a science fiction novel written in the mid-20th century. Set in a futuristic universe where humanity has colonized the far reaches of the solar system, the story revolves around John McBride, who is stranded on a manmade version of Hell on the planet Pluto. The narrative explores themes of familial duty and the bounds of human endurance as McBride desperately seeks a way to return to his pregnant wife, Enid, who is critically ill and needs him by her side. The plot follows McBride's frantic attempts to secure passage back home after receiving news of his wife's condition. Encountering a series of technological hurdles and the eccentric crew operating an experimental spaceship called the "Haywire Queen", McBride uses his engineering knowledge to help repair the ship and try to hasten their journey. As they face extreme challenges, including a malfunctioning drive that causes the ship to exceed the speed of light, McBride's determination to reach Enid remains the central driving force. Ultimately, he arrives just in time to witness the birth of their son, linking the title's concept of a "latent image" to the newborn's resemblance to his father and the culmination of his struggles.
