Blind Seed by Olivia Gaines

At a remote campsite in the mountains of North Carolina, a woman arrives seeking the protection of Boyd Glover, the technician known as Falling Rocks.
Falling Rocks is renowned for being a careful, meticulous planner who leaves nothing to chance. He thinks everything through, six times over, before making a move or a decision. However, the skills of the accident specialist paled in comparison to their team leader, The Archangel. A leader, three steps ahead of everyone in the game, especially Falling Rocks, who enjoys the life of a loner.
Charlotte Worthington didn’t want to be under the protection of such a man, nor to be forced into his company, but she needed a change in her life. If the Archangel said this is where she needed to be, then she trusted his guidance. She understood why Falling Rocks was chosen to be her champion, and also realized he was the man the Archangel had chosen to be her husband.
Too bad no one told that to Falling Rocks.
