Playing with the Boss by Cherry Carpenter

Fire pushes out a lot of secrets at Smith Enterprises.

Fiona has secretly adored her boss almost as long as she’d worked there. Although he’d flirted with her at an after work party, she’d never believed he really noticed her outside of being a great worker. Then the breakroom caught on fire.
Things began to unravel, and she’d become a target for someone who’d escalated from theft to arson. Nicholas, a power in the boardroom which he wielded like a sword hidden behind a shield of silk, finally made his feelings known to her. He brought out a submissive side of her she wanted to explore. But would they have time amidst the office turmoil and threats to her safety?

Or would her enemies push her out of the office and out of Nicholas’ life before she had a chance to see where their relationship could lead?
