Joe Ide signed Hi Five, the fourth book in his IQ series, at The Poisoned Pen Bookstore in Scottsdale last night. The book tells the story of Christiana, a young woman with multiple personalities who just happens to be the daughter of the biggest arms dealer on the West Coast. She is also the sole witness and the primary suspect in her boyfriend’s murder. Private investigator Isaiah Quintabe must piece together information from five different personalities in order to solve the case.
