Chief Radvar by Crystal Dawn
Chief Radvar's ship and crew go through a space anomaly and find they've gone back in time and somewhere so far away in space that they don't recognize where they are. A scientist suggests they might be near Earth. But that was a legend that didn't really exist, right? Shay finds that her whole life changes when two alien space ships start orbiting Earth. The aliens on one ship are definitely the enemy but are the others as benevolent as they seem or just self serving?
