I bought this book after reading some glowing reviews about it but I didn't like it at all. Tessa is portrayed as a quite immature woman. Her husband goes off to study in London and doesn't return to the family home when he comes back and Tessa doesn't demand to know what's that all about? She goes to talk to him when she finds out her 'mother' is not her birth mother and he tells her, at such a critical point in her life, that he's having an affair? I don't know why I didn't give up at that point. She then set about finding her birth father and is totally obsessed with him to the detriment of her own family. This is what Tessa thinks of prison at Location 2545 - 'It must be terrible for all the men in there to be at the mercy of an outside world over which they had no control,' at this point you just have to suspend belief.
I hope that the title was Ms Grey's attempt at getting the readers to wonder just who was the Bad Mother - Tessa, her birth mother or her adoptive mother? If it was aimed solely at Tessa, I'd have to question that.
I can be quite pedantic and things like ' "You must travel a lot" asks Tessa' really annoy me as making a statement is hardly asking a question and ' "No" agreed Hugo' would read far better if it was ' "Yes" agreed Hugo'. I know some readers will think I'm fussy but a storyline really has to have some credibility for me to enjoy it and prose must also be thought through, not just the case of stringing words together without some thought.
