'Kala never wanted to be a hero. She was a junior scientist studying under the highly-respected Commander Stanos when her station was attacked.
'The threat is unlike anything Kala could have imagined: the aliens are fast, overwhelmingly strong and pathologically intent on killing any human they encounter. Worse, they have a flawless disguise. Once they kill a human, the aliens absorb its body and assume its skin.
'But Kala thinks she's discovered their weakness. And her knowledge might be humanity's only hope.'
