Fraternal twin to a glamorous supermodel, Ailee Klein knows her place. Even if her parents hadn’t continuously told her she wasn’t particularly pretty or smart, she realizes her crush on her boss Josh Huxley is hopeless, especially when her sister is set on marrying him. So Ailee starts a serious relationship with another man to get over him.

Underneath a veneer of success and respectability, billionaire lawyer Josh Huxley carries psychological scars. Dubbed the one most like his psychopathic mother, who tried to kidnap him and his brothers when he was eight, he suppresses his dangerous urges for revenge and puts on a mask to fit into his family and keep everyone safe…not just from his mother, who’s still at large, but from himself.

The only woman who can soothe the jagged edges of his mind is his sunny assistant Ailee. When she’s bullied and publicly humiliated by her cheating fiancé and family, he steps in to protect her, and impulsively declares they’re engaged.

After her apartment burns down, she moves in with him. Their forced proximity cracks his mask, and he tries to stay away, afraid of tainting her sweetness with his darkness. But every smile and thoughtful gesture from her chips away at his defenses until he’s left yearning for her. When enemies from his past threaten her safety, he’s put to the test: how far will he go to protect her...?
