My Enemy's Son, My Only LOVE!

She was ten when her father was convicted of something he had not done and died for it. She trained as a lawyer and spent years on the case. Her way back into it was the son of the man she held responsible, and she got close to him under a name and a story that were not hers. He saw through it at the start. He had known something about her father's case for ten years and had never said it out loud, and he let her keep the story going. Each of them kept testing the other, and what was between them stopped being an act. The old case was reopened while this was going on, and what had actually happened to her father began to come out.
