Pangu's shadow

"There are no second chances in the Pangu Star System. Ver and Aryl, apprentices at the most prestigious biology lab among the system's moons, know this better than anyone. They've left behind difficult pasts and pinned their hopes for the future on Cal, their brilliant but demanding boss. But one night while working late in the lab, they find Cal sprawled on the floor, dead. Murdered. And they immediately become the prime suspects. Their motives seem obvious. Ver, who left her home moon to study the life-threatening disease wracking her body, had a hopeless attachment to Cal that could've become twisted by jealousy. Aryl, on the other hand, clashed with workaholic Cal because she valued more in her life than research. To clear their names, Ver and Aryl put aside their mutual suspicion and team up to investigate Cal's death. As they search for the real murderer, they uncover secrets that have shaped all of Pangu's moons ... and must decide what kind of future they really want."--Book jacket.
