An Agent for Cecily - Pinkerton Matchmakers, #8

There's only one way to escape Cecily Sheldon's insane family - take on someone else's identity. Along with this new identity comes a new job. Of course, to become a Pinkerton Agent, she must marry a male agent who will train her. Now she needs to keep her true identity hidden from Broderick Tanner for fear he'll arrest her along with her father and brothers. Perhaps living a double life wasn't a good choice after all.
