Tylar Daire is the navigator on a space mission whose focus is to discover a cure for a mysterious illness killing colonists on Terra. The crew consists of the captain, a soldier for protection, a scientist to study the virus, Tylar himself, and hot-shot ace pilot Rion Z'ev. From the moment Tylar and Rion meet, sparks fly. They try their best to keep their growing relationship from the others, but when they're alone on the bridge during the day, or holed away in the sleeping quarters at night, they can't keep their hands off each other.
Soldier Jareth is an old friend of Tylar's. When he begins to suspect he's caught the virus they're trying to cure, he swears Tylar to secrecy. But Jareth gets worse, until he can't hide it any more, and he collapses out in the field. Will the crew be able to defeat the virus, or is it too late to save them all?
