Portal's Gift

The most famous astronaut on earth discovers hyperspace has interesting consequences when he is marooned with his alien shipmate.

When Earth joins forces with the friendly Teneran aliens to gain access to their hyperspace drive, Josh is the first human to copilot with a Teneran commander. On the Marco Polo, a Terran ship equipped with the alien drive, he and the enigmatic Teneran Paris explore distant worlds no astronaut from earth could have visited without help from the aliens.

Not until a blinding sandstorm maroons Josh and Paris on a desolate planet does Josh realize the implications of the Teneran drive. He finds himself unaccountably attracted to Paris. Will his travels through the portals of space change his life forever?
