Parasite - Alpha Quadrant Time Travelers, #2

An alien fell through time to Earth, 2020 where he met the physicist about to discover time travel. Bay Mackie isn't your typical physicist. Armed with combat boots, a killer glare, and fishnet tights, when she meets the time-traveling alien, Zel, she knows exactly what to do... Follow him on his adventures through space and time. She can always defend her Ph. D. thesis when she gets back. There's only one problem.
Zel's secret. Bay doesn't know that Zel is more than what he seems. As their feelings for each other develop, Zel can't hide the truth. Bay has to make a choice: return to Earth or run across the universe with an alien she barely knows.
