In Prey, the best-selling author of Infidel, Ayaan Hirsi Ali, presents startling statistics, criminal cases and personal testimony. This violence isn't a figment of alt-right propaganda, Hirsi Ali insists, even if neo-Nazis exaggerate it. It's a real problem that Europe--and the world--cannot continue to ignore. She explains why so many young Muslim men who arrive in Europe engage in sexual harassment and violence, tracing the roots of sexual violence in the Muslim world from institutionalized polygamy to the lack of legal and religious protections for women. Deeply researched and featuring fresh and often shocking revelations, Prey uncovers a sexual assault and harassment crisis in Europe that is turning the clock on women's rights much further back than the #MeToo movement is advancing it.
