A sweeping young adult Christian fantasy inspired by the Book of Revelation, Host World reimagines biblical prophecy through intergalactic adventure, exploring faith, neurodiversity, and the hope of redemption in a universe on the brink of its own apocalypse.

Thirteen-year-old Elroi has spent her life knowing the day would come when she'd be taken from her family. Selected for Earth's controversial Imaginarium program, she's renamed Ashtore and sent across the stars to Jokull—a magical world where ancient prophecy, fractured kingdoms, and four dying Gems hold the fate of an entire planet.

As Earth's leaders seek to exploit Jokull's power, Ashtore is drawn into a centuries-old spiritual war between the faithful Christos and the enigmatic Kokabiels. Torn between promises of power that could save the brother she left behind and a mysterious hope that calls her to something greater, she'll have to decide whom to trust before a prophecy unfolds that no one can stop.

As darkness spreads and the Four Torments herald the coming Great War, Ashtore discovers that faith is more than belief— it's standing firm when everything is at stake.
