The Fall of Sirius

When the vast armada of Waister starships had swept through human space, destroying entire star systems as they came, Malyene Andreivne along possessed the initiative to save a desperate few in cryostasis. But that was 2,000 years ago. Now she has been awakened from her slumber, and everything she once knew has long since turned to dust. What's more, the strange beings who wrenched her back from the timelessness are the descendants of a union once considered unthinkable - half human, half Waister. And as Malye struggles to understand the unlikely inhabitants of her new world, they all face a crisis that none of them may survive - for the Waister ships are returning.
