In Their Shadow by kisupure
The full synopsis:
Galen’s a 15-foot extraterrestrial and member of one of Yellowstone’s professional search and rescue teams; Holly Mendoza’s a 29 year-old “runaway” just getting her new life started in Montana. And while a broken leg in the Beartooth Mountains brings the unlikely pair together, it’s when they discover a shared isolation and bitterness between them that they decide to stay in touch.
She finds it easy to open up about her baggage to the near-stranger, but she knows far less about him than she thinks… and it’s all Galen can do to keep from telling her the deadly secret of who he really is.
Little do either of them know, though, that it doesn’t take full disclosure about extraterrestrials to throw everything they know into chaos.
