What if love could survive the end of the universe?
    Dr. Mira Sen has spent six years believing the man she loved is dead. Then a mysterious signal from a dead star calls her name—and tells her to find Elias Vale.
    When Elias suddenly returns from beyond the known universe, he brings a terrifying warning: ancient Gates are opening across space, civilizations are disappearing, and a mysterious force is feeding on the memories of intelligent life.
    Their journey leads them to the Garden, an ancient world holding the secrets of countless lost civilizations. But the Garden demands an impossible price: to save the universe, Mira may have to sacrifice the one thing she cannot bear to lose—her memories of Elias.
    As they cross dying stars, alien worlds, forgotten civilizations, and the boundaries of space itself, Mira and Elias discover that their greatest weapon is not technology or power, but a love that refuses to disappear.
    The Last Horizon is an emotional science-fiction adventure filled with mystery, romance, sacrifice, cosmic wonder, and the timeless question of how far we would go for the people we love.
