In the quiet town of Evergreen Falls, New York, hardware store clerk Jasper "Jazz" Harlan discovers three ancient glowing embers hidden by his late Aunt Mabel. As he gathers them with help from his girlfriend Lena and best friend Tommy, he awakens to his role as reluctant guardian against the Hollow—an ancient darkness threatening to devour light and life. From attic finds to desert burials and a final confrontation in his own home, Jazz learns that eternity’s last sparks are carried not by magic alone, but by stubborn human courage, friendship, and the small, everyday acts that keep the darkness at bay.
