What a brilliantly written and well researched book. It reminded me very much of Fingersmith by Sarah Waters, but most certainly came into it's own thanks to the strong main character of Anna Palmer.
Anna has been committed to Lake House, a place of rest for genteel ladies by her thoroughly unpleasant husband Vincent, a vicar who is hiding his cold and despicable personality behind his dog collar. Powerless to do anything when she realises Lake House is an asylum in disguise, Anna searches for ways to escape, but this comes with dragging days in which she feels completely isolated from the world apart from her wiry attendant Martha Lovely and the other lady inmates. The question is of course - are they really mad or has Lake House made them that way.
A very good first book with the plot and characters nicely portrayed, all in all an excellent read for those interested in Victorian fiction.
