There is one book that has stuck in my mind over the years, probably because I was so young when I first read it.
It is a semi-autobiographical novel about a sixteen year old girl who retreats from reality into the threatening kingdom in her mind. It tells of her stay in a mental asylum, and her long struggle back to sanity.
Her descriptions of the behaviours of her fellow inmates of the asylum are graphic and disturbing.
Not sure who wrote the book – ‘I Never Promised you a Rose Garden’ but I must look it up and read it again.
