Handsome Devil by L.J. Shen

 Gia Tatum Blackthorn is Lucifer personified. A monster from my nightmares, now masquerading as my boss. When he discovers my weakness, he makes me an offer I cannot refuse, and I become his wife.

I always knew he was depraved, but as his twisted vendetta unfurls, so does my darkest secret. Now we're both the targets of very nefarious people . .

. but they're about to find out no one matches my husband's wrath. Tate I am a man of few pleasures, one of which is taunting my secretary, Gia Bennett.

But after I blackmailed her into becoming my bride, it's clear my fixation has no limits. When my revenge spree sparks into an all-consuming mafia war, it isn't just my life that's on the line. And in this chess game, the king protects the queen . . . even at the price of losing his entire empire.
