Wanted to like this book more than I did, as it combines two of my big loves - 20th century historical fiction and books!

Twenty years ago, Hazel's younger sister disappeared on her watch, presumably drowned in the fast-moving river Thames.  Hazel has never really believed in her death, and as such never moved on from her grief.  On her last day at work in a bookstore she unwraps a package containing a book which tells the exact same story she  used to tell her sister when they were evacuated during the war.  Nobody else knew the details, so who wrote the story?  Is Flora alive?

I quite enjoyed the back and forth in time, each chapter telling us a little bit more about Hazel's journey to the truth, and the events that led up to Flora's disappearance, and why Hazel blames herself. 

I did, however, find the ending somewhat unsatisfactory with everything neatly wrapped up and no real hint of the heartache that  would in reality result from that situation.

I also get irritated by non-British authors who make fundamental mistakes about British life, and whose editors do nothing to put those errors right!
