His Lost Mate by Theresa Hissong

Nash Ward, alpha to a pack of white wolves, took his role as leader very seriously when his family and pack were almost destroyed by a clan of bear shifters ten years prior. It became his duty to protect the remaining four members, but when a human female shows up, scenting of his mate, his carefully hidden world opens up.

Isabell Palmer, a journalist and survivalist, travels north from her home in Anchorage to spend four days on a solo hike. She hires Ward Air & Transportation to fly her into the remote location to start her journey, taking photos and gathering information for her article on backpacking locations in the state. She doesn’t expect to be thrust into the world of the paranormal.

Nash immediately notices the female, but the need to keep his family’s secret safe outweighs the desire for a mate. Until the night he loses control, revealing himself to Isabell.
When the truth comes out, will she run far away or stay with him even though they live in fear of being hunted at every turn?
