Undercover Lover — Tibby Armstrong

Book two in the Covert Attractions series. Good girl Jenny Ainsley never hoped for more than her nine-to-five existence. Then her famous brother hires a bodyguard to protect her--a sinfully sexy man who gets drawn into a plot to take down an international drug syndicate. At first an unwilling participant, Jenny soon realizes she has the opportunity to break away from her timid past and do something important. And getting her hot bodyguard into bed will be a delicious bonus. He resists her at every turn, however, and she discovers that no amount of training--or seduction--can crack the code to this man's heart.

Ex-MI-5 agent Gunter Faust is no stranger to watching the beautiful Jenny Ainsley. For years he's seen to her safety, hiding in the shadows and pining for the woman he can never have. Bedding a client is not an option. But fate has put her by his side, working up close and personal. And with Jenny's relentless determination to seduce him, it's only a matter of time before she blows his cover--and his heart--wide open.
