Time is running out for the Milky Way. The galaxy continues to be overrun by the invading Horlan. Hundreds of worlds are being consumed, and entire civilizations are threatened. On the other side of a jumpgate, three science vessels are stranded in another galaxy. Their research could mean the difference between victory and extinction, and HMCS is being sent to bring them home. But one science ship has its own agenda, one can't be found, and one doesn't seem to to be found. Isolated and alone, the crew wonders if it's already too late for their homes and loved ones. Nerves fray and tempers flare as they struggle with the prospect of being humanity's last hope. Dillon and his battered crew must navigate not only the dangers of a long-dead civilization, but the dangers they pose to each other. Their chance to save humanity will come in an unexpected form, and at a high cost.
