A love that defies time. A mystery that spans fifty years. In the spring of 1975, eighteen-year-old Ethan has his whole life ahead of him. The Vietnam War is finally over, and he's preparing for college and a future with his childhood sweetheart, Lisa. But seeking a moment of peace before the next chapter of his life begins, Ethan takes a solitary camping trip into the Appalachian foothills-and discovers a glowing, perfectly symmetrical cave that defies all logic. Stepping inside, Ethan is transported to an alien, untamed world. Trapped in a landscape of bizarre creatures, strange celestial skies, and unexplainable temporal anomalies, he must rely on his wits and his journal to survive. For fifty agonizing years, his only tether to sanity is his memory of Lisa. Meanwhile, in our world, Lisa refuses to give up hope. As weeks turn into decades, she carries the torch of their love, searching for answers while Ethan is presumed dead. When a miraculous convergence of time and space reopens the portal in 2025, two lifetimes of grief, survival, and enduring love collide. Will time give them a second chance, or are the laws of the universe too powerful to break? Perfect for fans of The Time Traveler's Wife and Outlander, Just In Time is a gripping sci-fi romance that explores the boundless limits of human endurance and the unbreakable bonds of true love.
