Knotted

Read Knotted Storyline:

A woman with a green thumb is married by proxy to a noble who has a secret life commanding shadows. Gardener versus Guardian.
Rowen went along with her niece to apply for the Volunteer project, and when she is asked to participate, she has to decide if the stars are for her. When they offer her an entire world full of gardens, she is hooked. There is only one problem, no alien can work on the surface of Irudan; they must be married to a local to work there.
Skorin Nakkua wants to get his family to stop asking him to get married, so when a marriage of convenience is requested by the Alliance, he agrees. His wife will live on Irudan and take on his social responsibilities with the community, leaving him free to focus on his life as Walking Darkness, the head of the Irudan Guardian Base.
He had never expected their paths to cross while he was on duty, but the new Lady Nakkua is far more than he imagined and the convenience of their marriage begins to chafe.
