A spaceship hurled four billion years into the future faces dangers as it searches for home in this space opera adventure by a New York Times bestseller. Lord Commander Grayson St. Clair has guided the Tellus Ad Astra to a part of the universe no human—and possibly no race known to Man—has ever seen. Far from the worlds they know, the colony ship is on its own, facing . . . something that seems to have no weakness. Something whose sole purpose seems to be devouring civilizations. With both time and space as enemies, St. Clair must figure out a way to explore this new corner of space, maintain military order on a mission that was supposed to be civilian, and—somehow—bring the Tellus Ad Astra back to the Milky Way. Combining the drama and action you’ve come to expect from military science fiction master Ian Douglas, this follow up to Altered Starscape is bound to capture your imagination. Praise for Darkness Falling “Douglas’ use of description is exceptional; readers vividly see the scenes as they unfold, just as if they were there. While being true to the classic sci-fi genre, Darkness Falling also tackles deep issues of ethics and morality. Fans of Douglas will love this series, and the latest installment does not disappoint.” —RT Book Reviews
