Well, after staying up all night reading, book 5: Good Me, Bad me by Ali Land
Another one that was on offer on the kindle.
I raced through this - it's well paced and interesting, although you do have to suspend disbelief at times.
This is told from the point of view of Milly, a fifteen year old girl who has recently shopped her serial killer mother and relates her struggle to come to terms with who she is, whilst settling in to her Foster home.
It's quite surreal at times, and the court case wasn't handled particularly well, with all the focus seemingly on the last victim when eight bodies had already been found buried in her mother's cellar.
As odd as it sounds, her mothers crimes are very much in the background and not really detailed at length - whilst the author should be applauded for avoiding deliberate shock tactics over what is a shocking situation, it is difficult to figure what motivated her mother, which adds to the unbelievability factor. In some ways, it's quite a clever device as the narrator comes across as quite unreliable.
The twist at the end was a bit predictable.
Overall, a decent albeit unsettling read, and for only a quid on the kindle.
