Masked Desire by M.A. Lee

One rule: wear the mask.
Second rule: never reveal your identity.

Lily Carter wanted one reckless night—no names, no consequences. But when a mysterious, powerful man breaks the rules, their connection becomes impossible to forget.
Damon King thrives on control as the feared owner of an underground club—and a mafia king. Yet one masked woman shatters his carefully guarded world. When he learns who Lily really is, he can’t let her go.

Drawn into danger, Lily becomes a target for Damon’s enemies, forcing him to risk everything to save her.
Because once Damon claims something… he never lets it go.
