The Rhythm Section Book by Mark Burnell, review of the book to movie

The Rhythm Section begins with the crash of flight NEO027. The crash destroys Stephanie Patrick's life: her family was on board and there were no survivors. Devastated, she drops out of college and her life spins out of control as she enters a world of drugs and prostitution--until a journalist discovers that the crash wasn't an accident. There was a bomb planted on the plane. Filled with rage, and with nothing left to loose, she focuses on one goal: revenge. The opportunity to obtain it arrives quickly when Stephanie is approached and recruited by an extremely covert intelligence organization. She is young, smart, and beautiful--and has no family, making her the perfect candidate. The organization offers her a deal. She must undergo rigorous training; learn how to control her heart rate and breathing; and learn how to efficiently use weapons. Then, she will assume a new identity and commit acts of terrorism on behalf of the organization. When she completes these assignments successfully--and proves her loyalty--she will be offered the opportunity to take out the terrorists who brought down flight NEO027.
