A trip to Norway with her girlfriends was supposed to be a once-in-a-lifetime trip for Cathy. After being made redundant and dumped by her power-hungry ex, it turns into a much-needed escape before piecing what remains of her life back together. The picturesque country is an ideal launch pad for her new career as a photographer too. But what she captures on her camera, she couldn't have imagined in her wildest dreams.

Ærlen has one mission in life: protecting the forgotten valley that is home to his community of trolls, huldra and other magical creatures- the Hidden Folk. He is loyal and ambitious, with his sights set on becoming the next chief of his village. Yet something vital is missing; to become Jarl, he needs a mate, and prospects are rare. When female voices are heard in the valley and his team is sent to scout out the threat, he is captivated by a beautiful brown-haired stranger with a camera.
He has to get the photo she took or risk his already endangered people being discovered. But, as the Stone Trolls wake, his camera retrieval operation becomes a rescue mission, one that puts his own life at stake.

Sparks soon fly between the unlikely pair and as the rescue helicopters circle above, the threat of being discovered draws ever closer. Decisions must be made.
Ærlen knows he does not want to live without Cathy, but can she give up everything and everyone she has ever known for a life in secret...with a troll?
