Star Trek: Invincible Book One (Star Trek: Starfleet Corps of Engineers)

STARFLEET CORPS OF ENGINEERS
One of the S.C.E.'s top officers, Commander Sonya Gomez, is assigned to supervise a project on the crystal planet of Sarindar -- helping the reclusive and hostile Nalori harness a valuable new ore. Morale is low and the project is behind schedule. Gomez must get the workers up to speed and on track -- a task made more difficult by the Nalori workers, who do not want her there even though their government does.
Just when Gomez begins to gain their trust, two workers are killed by a mysterious local animal called a shii. Gomez must learn the secret of the shii before it kills again....
The first in a gripping, all-new two-part adventure!
