Excellent book. Lots of action and twists and turns around every corner. Although it is not necessary to read the previous Jack Tobin books, you may want to read them so you become familiar with the characters and the author's "style." There are a lot of courtroom scenes that are a little technical, but if you read legal thrillers and/or watch legal TV shows, you won't have any problems. Will he write a sequel to this book? I am looking forward to more by Jack Sheehan. Move over John Grisham and James Patterson.
