Lucy Galloway is the daughter of the two most famous spies no one has ever heard of. As a woman, it hasn't been easy to build a career as an agent. She fought against all odds to rise to the top and earn a spot among the Royal Saboteurs. Imagine her annoyance when too-good-to-be-true Duncan Slorach continually bests her at training camp. The man isn't just good at codes and hand-to-hand combat, he never accidentally blows anything up. So when Lucy is partnered with Duncan on her first mission, protecting the eldest son of the prime minister, it's the second worst part of the assignment. The first is that she must act as a nanny to the prime minister's young son. What is she supposed to do with a six-year-old all day?

For eighteen months, Duncan Slorach trained to be a Royal Saboteur. He's one of the best, and when he's finally offered a mission, he jumps at the chance. The only problem? His partner. For eighteen months, Duncan has been in love with Lucy Galloway. Unrequited love. The woman barely seems to know he's alive. Duncan is ready to put his feelings aside and concentrate on the assignment, but that proves impossible when Lucy and Duncan are forced to spend long hours alone together and begin to build a friendship. Surely, if he could just kiss her, she'd realize she has feelings for him too.

As Lucy and Duncan draw closer to discovering the traitor in their midst, they realize nothing is as it seems – with this mission or their relationship. In fact, Duncan isn't the villain Lucy has made him out to be. In fact, he might just be the scoundrel she's been looking for all along.
