Even having finished this book I'm not totally sure what I made of it - ultimately I thought I'd enjoy it more than I did, but the challenging subject matter likely affected "enjoyment".

I did prefer it to Girl A, mainly I think because this setting and these characters felt more real, more like the author actually knew what she was writing about.

At times, particularly the sections about the "Truth Seekers" this was a disturbing read, that people can actually accuse parents of faking their kids' deaths, or denying that the kids ever existed.  I liked that the ending left things slightly up in the air, for the reader to make up their own mind
