The Daredevil by Nadia Han

Loving her is his biggest risk . . . and also his biggest reward.

Daring, clever, and gorgeous, Royce Viktorsson is a volcanologist who lives life on the edge between the thrill and the pulsing calm before the storm. His unsteady lifestyle masks the man who is seeking to heal the hole in his heart. Nothing has offered him resolve . . . until her.
The lightning that illuminates his soul.
The thunder that stirs his heart.
The lava that ignites his blood.
Thoughtful, alluring, and guarded, travel blogger Michelle Yates is emotionally unavailable thanks to the monster in her closet. Traveling allows her to see the beauty in the world, making her forget the ugliness in her life. One man yanks on that closet door and helps her claim back her self-worth.
The friend who becomes her lover.
The hero who defeats her monster.
The savior who defines her destiny.
As their romance churns, danger erupts, whipping out secrets that demand the truth, but the daredevil is willing to risk everything to defend those important to him.

The Daredevil is a friends-to-lovers, fake-dating, forced proximity, destined moments, billionaire hero, and a suspenseful contemporary romance. It is Book Two in the WaterFyre Rising series but can be read as a standalone.
