City of Veils by Zoe Ferraris
This is a beautifully written novel with an intriguing crime story running alongside a detailed description of the way of life in Saudi Arabia that both teaches and captivates.
It is fascinating and tense and the romantic thread is absorbing in this totally different culture – it is a who-dun-it that is so much more than an ordinary crime story, it keeps you guessing until the last moment.
