Marina Lansky has always dreamed of being a spy, but when she gets recruited by the Mossad in her junior year in college, she gets more than she bargained for. Her growing obsession with Ali Chalabi, a fellow student from Saudi Arabia, sets off a chain of events that take her from New York to Riyadh to the Arabian Desert and almost cost her life.
When Marina learns that Ali has broken into Israeli military computers and plans to help Palestinian terrorists, she volunteers to help Israeli intelligence track his activities. After Ali is recalled home to work for the Saudi Defense Ministry, she marries him in order to continue to spy on him. In Riyadh, she is caught and condemned to death for being a Zionist spy. She is taken up over the desert in a helicopter piloted by Ali and forced to jump. Having survived, Marina realizes that Ali risked his life to save her. Saudi religious authorities declare her survival a miracle that Allah performed because Marina became a Muslim. She is pardoned and turns into a local celebrity. Reunited, the couple returns to New York where she faces Mossad again and must decide between her lifelong allegiance to Israel and her love for Ali.
This is a synopsis.
A hook requires more than "what this book is about". There needs to be an enticement to read it. What's the central decision that Marina has to make? What are the stakes? You can't just describe her like a dossier either. She needs to have substance so we'll want to read on.
I also want to know how she survives jumping out of a helicopter.
