Cade "Hercules" Thornton is an ex-marine and soldier of fortune; now he's the owner of Hercules Security, which provides the best bodyguards in the business. Since his leg was crushed and reconstructed, Cade doesn't do field work anymore - until a challenge is issued to him by wealthy Kate Morgan, who wants her bookish grandson protected from a stalker. She insists on having the very best bodyguard available, and that is Cade himself.
But there is nothing laid back or bookish about Dr. Jude Morgan. Having lived under the thumb of his grandmother his entire life, Jude is insistent that he doesn't need a babysitter. Sparks fly when Cade tries to insinuate himself into Jude's life, and Cade knocks Jude on his ass - literally.
Yet the danger to Jude is real, and Cade is the only thing standing between him and an increasingly more terrifying stalker. Cade's protective feelings for his client become something more while Jude begins to realize that his brawny, neo-Viking protector is a man unlike anyone he's ever known. Yet as Cade and Jude grow closer, so does the danger.
Cade will stop at nothing to protect Jude, but Jude's stalker is determined to get his man - even if he has to kill Cade Thornton to do it.
