Project Charon 4: Swarm - Project Charon, #4

Tina and her crew finally arrive on Olympus, the world that holds the Federacy Assembly. Her initial plan was to go there to present the data the left in a locker on Kelso Station fifteen years earlier, but many things have changed. For one, rather than wait for someone else to do it, she and the scientists they collected at Aurora Station have been working on a cure for the infection that turns people into grey-skinned mutant pirates.
Secondly, they're bringing a stricken war ship and a few of its remaining crew members who were rescued from pirate captivity. Little has gone to plan. After a few attempts, they don't yet have a cure. And while the infection does horrendous things to people besides giving them a long, but miserable, life, it seems that the only way it spreads is through human intervention. Tina and her friends are about to make a few discoveries about power, who wields it, and how it is used in this conclusion to the Project Charon series.
The betrayal runs much deeper than anyone has predicted. Those in power are not going to take their uncovering lying down.
