Invincible

Assigned to help the reclusive Nalori harness a valuable new ore on the crystal planet Sarindar, Starfleet Corps of Engineers officer Sonya Gomez inherits a demoralized crew, a workforce that resents her presence, and a project badly behind schedule. When workers start dying, killed by a creature the Nalori dismiss as myth, Gomez must prove the shii is real and stop it before the project, and its people, are destroyed.
