At first glance, this book and its contents make you eager to begin reading. But unfortunately this is not true in real life as the reader will find out. The premise of the novel seems intriguing but I found out quickly that it didn't deliver. The main characters, Jack Morgan and Nick Stone were shallow at best and unbelievable at worst. Both were supposedly "professional" assassins even though they spent practically all their time hunting down criminals.
Bad review
