This book studies the radical Islam movement in Saudi Arabia from the 1960s to 2019, and exposes the causes of female terrorism and extremism to highlight the dark tunnel of such radicalism and to help others to recognise it before it is too late to be redeemed. It highlights radical women as having a dangerous impact on Saudi women, especially university students, showing that, although al-Qaeda was not keen on involving women in terrorist operations, that does not mean women were totally uninvolved.
