Book Cold Welcome — Elizabeth Moon

Admiral Ky Vatta should return to her childhood home a war hero, but on the way her shuttle is downed by sabotage.
Marooned in a hostile landscape it'll take every bit of wit, skill and luck she can muster to lead her fellow survivors to safety, knowing that the mysterious enemies who destroyed the ship are on the hunt, and may have an agent in the group ready to finish the job at any moment. And was the sabotage an attempt on Ky's own life, or someone else's?
