After the shocking ending to Mind Games, Justine finds herself engaged to Otto, and the wedding is a few short days away. She should be happy, but she is plagued with headaches that are brought on whenever she thinks about the murder of Avery. The city is under martial law, crime is rampant, and everyone is gunning for Packard. So why is he hanging around? Justine needs to find the truth, and free her friends before it's too late.Head Rush is a great ending to a great series. I love just about everything about these books. They are quirky, funny, exciting and entertaining. A rare case of getting to the end of a series and thinking, 'I would have liked a little more.'
