Love letters to a serial killer

When Hannah Wilson first hears about the dead women in the news, her interest in the murder case is healthy. Enough. Like the other women trawling the true crime forums, she's convinced that she could be the one to put the pieces of the puzzle together online. Solve the murders. Somehow. Maybe solving the case would make her feel okay about getting fired. Maybe it would make her sort-of-boyfriend love her. Maybe. And then handsome lawyer William Thompson is arrested. And Hannah is so full of female rage about everything he's done and everything she's going through, that she decides to write him a series of angry letters. She just doesn't count on him writing back. Her new pen pal feels like an exciting adventure at first. But when William is released, when she finds herself engaged to him and living in his home, she must wonder if her obsession has gone too far.
