Romantic-turned-cynic Sierra Callahan is a broke branding consultant in San Francisco who's gone off men. Desperate to save her home and family business from bankruptcy, she agrees to a marriage of convenience with über-rich, marriage-averse Michael Donovan, who needs a bride fast to satisfy his ailing father. Only thing is, their business arrangement has to look like the real thing-even to their closest friends! Sierra and Michael fight a sizzling, most unbusiness-like attraction. But attraction isn't nearly as scary as their growing feelings. When a man from Sierra's past surfaces and threatens blackmail, will that destroy the no-strings marriage contract-and any chance of happiness Sierra and Michael have?
