I am answering a question publicly asked private again. It’s something someone wanted to know in the Immortal Lover.
Question: Is Ana aware she was causing so much pain and destruction by time walking?
Answer: In most cases she isn’t aware and the few times she were; her own agony took front seat. The overwhelming torment of her own pain blinds her to the consequences of stepping back in time. If you read the first book you’ll get a better understanding of why she does the things she does.
