Rock Hard - Nalini Singh

In New York Times Bestselling author Nalini Singh's newest contemporary romance, passion ignites between a gorgeous, sinfully sexy man who built himself up from nothing and a shy woman who has a terrible secret in her past...
Wealthy businessman Gabriel Bishop rules the boardroom with the same determination and ruthlessness that made him a rock star on the rugby field. He knows what he wants, and he'll go after it no-holds-barred.
And what he wants is Charlotte Baird.
Charlotte knows she's a mouse. Emotionally scarred and painfully shy, she just wants to do her job and remain as invisible as possible. But the new CEO-a brilliant, broad-shouldered T-Rex of a man who growls and storms through the office, leaving carnage in his wake-clearly has other plans. Plans that may be equal parts business and bedroom.
If Charlotte intends to survive this battle of wits and hearts, the mouse will have to learn to wrangle the T-Rex. Game on.
