Details: 

Her brother's best friend claims she's not his type, but then he suddenly shows up at her apartment...

Magnetic, brilliant, and achingly stunning, Remington Starke is a dangerous man with a vision, a mission, and a threatening past that haunts him. That alone should keep him away from the only woman who has ever made him feel anything.

Creative, cautious, and canny, Audri Wu is imprisoned by a guilt that torments her soul. Despite the darkness, she sees the rainbow in the rain and the spark that lies beyond the hardened façade of a man who has a reputation for shattering hearts.

Her boss.
Her protector.
Her brother’s best friend.
Water to her fire.

As their romance begins, that past catches fire and burns away the lies, revealing deadly secrets that could destroy them both.

The Mastermind is a brother's best friend, billionaire boss, and a suspenseful contemporary romance. It is Book One in the WaterFyre Rising series but can be read as a standalone.
