James, Hannah, and Wolf face their greatest challenge yet in the pulse-pounding conclusion to The Rift trilogy. "Just when you thought the story couldn't get more riveting, Richards and Calvert dazzle, saving their best for last." Finally reunited on an advanced, alternate Earth where the mighty Roman Empire never died, James, Hannah, and Wolf now stand at the precipice of an interdimensional war threatening to obliterate everything they've fought to protect. As the fabric of existence continues to unravel, unleashing anomalous storms and creating rifts large enough for unstoppable warships to traverse, the trio must find a way to repel a superior force bent on conquest. Impossible, yes, but also just the beginning of their problems. Because they're in a battle for their very lives. And if the tears in the fabric of reality aren't completely mended, both worlds will ultimately fall, regardless of which side is victorious.
