Bridger by Geralyn Wichers

Global war has bled earth, and Char, almost dry.

Charlane “Char” Lee Thompson has sacrificed her health and her marriage to climb the ranks of the American Federation army. When a training accident wipes out her unit, Char is embroiled in a military scandal that leaves her career and health in shambles. Char leaves the army for private security and prepares to hide out at a remote research facility.

When a humanoid creature from another world appears one night, Char sees an opportunity to reclaim her career. She agrees to helm a covert mission to follow the creature back into his world. The plan: take its resources and gain an edge in the war.

But when chance meeting with her estranged husband dredges up old regrets, Char is torn between saving her country and saving the love she didn’t know still lived.
