Spirit Legend

Charlie, forester, guides her boss and the owner of Macallister Outdoors to a tiny lake in the middle of a wilderness tract he recently purchased so he can see with his own eyes the spirit that legend says lives there and uncover the truth about it.
Suddenly, a rogue storm destroys the dam that created the lake, the surrounding forest, and much of their equipment. They are stranded.
Then they see the spirit and hear it sing. It's real, it's beautiful, and it will die when the lake drains dry. They resolve to patch the dam and save the lake and the spirit.
As they work, they learn about the spirit of legend and about each other, while deliberately ignoring the growing attraction between them, because a romance between boss and employee is always a bad thing.
But some spirits can do more than just sing and look lovely. And romance has a way of developing even when it's not wanted.
