Uncertainty Principle - Singularity, #3

The Joias System-and all of humanity-is in deadly peril. The only way the motley group of human survivors, led by former diplomat Alba Espina, can prevent a massacre is to destroy the aliens' portal mechanism. But for a rag-tag party more skilled in diplomacy than demolition, stranded in an unfamiliar system, with both human and alien soldiers on their trail after their desperate escape from the aliens' capital-it seems like an impossible task.
And those aren't the only complications. There are other aliens in this system as well, ones that see humans not as enemies, but as prey. They're apex predators, and once they're on the hunt, they never let up. And they've caught the humans' scent .Uncertainty Principle is book three in the Singularity series, R. M. Olson's action-packed, epic space opera.
