After her childhood was shattered by unspeakable tragedy, Zoe has grown into a woman with walls so high, they're impossible to scale. And that's just how she likes it - especially given her line of work. As an accomplished computer hacker, she's made more than a few enemies in Boston's seedy underworld. When a freelance job brings her into contact with Parker West - heir-apparent to the biggest company in town - she has no interest in getting friendly with the billionaire playboy. But Parker's persistent charm is difficult to ignore... and the more time she spends with him, the more those high walls around her heart threaten to crumble. With dangerous foes closing in from all sides and the mystery of her tragic past finally coming to light, Zoe will be forced to reevaluate her priorities.
