Shy, intelligent widow Anastasia Whittig is really a Lady Spy in name only. Though she invents important items and decodes evidence, she’s hardly ventured into the field and keeps herself wrapped in a shroud of mourning for her late husband. She’s perfectly content to continue her sheltered life, but when one of her best friends is shot, she is forced into service at the side of Lucas Tyler.

Lucas is a daring, talented spy, driven to solve the case of attacks on his fellow agents. He doesn’t want any help, and certainly not from Ana. But as the two edge ever closer to the disturbing truth, they cannot keep from developing a grudging respect for each other. And they cannot ignore the undeniable desire that threatens to change both their worlds.
