Dana Sorensen spends her working life chasing 1's and 0's through complex systems and networks to protect her clients and their most valuable data. Just as she's approaching a crossroads in her career, an unwelcome assignment threatens to lead her down a winding path of deceit that goes well beyond the confines of the client's network. An unexpected reunion with an old lover and a suspicion of murder raise the stakes as Dana uses her head-and the help of unlikely allies-to unravel her client's darkest secrets before it's too late. In a tale that begins with a man and his mouse, Dana must navigate the perils of malware, rogue servers, and human passions to find the truth before the truth finds her. The Case of Mr. Porter and His Mouse is the first novel in the Dana Sorensen series.
