Crucible (The Carnathian Chronicles Book 1)

Extinction could be only a breath away.
When life support engineer Lela Masters began her tour of duty on Deneb IV, she expected to help repair the massive, ancient machines that supply atmosphere to the habitat domes of the alien Carnathians. What she didn’t expect was to fall in love…twice.
Lela happily offers her heart to her two Carnathian lovers, but when fear turns their people against the humans who have always been their allies will she choose to help save their race from extinction even if it takes her final breath?
