The Secret of the Brighton House

The Secret of the Brighton House has left me with mixed feelings. On the one hand it was a nice, quick read. The plot, on the other hand, well it wasn't at all what I was expecting.
The main theme of the book is postpartum psychosis, and how it was dealt with in the 1970's. Other themes include miscarriages, IVF treatment, difficult childbirth and attempted infanticide.
The secret of the title wasn't so much a secret as a massive big cover up.
The story is told across dual timelines. The present day is told in the third person and centres around Joanne who is pregnant and has found out that her mother, Grace, did not die giving birth to her, as she had been led to believe.
The 1970's timeline is told in the first person, from the POV of Grace. This timeline makes for very uncomfortable reading.
Quick read it may be, but there is a sense of unease throughout. Thankfully there is a happy ending, but it took me a while to shake off the sadness that had overcome me at reading Grace's plight.
