I am so… glad that I bought this book. One of the best mystery thriller I have come across. The protagonist is a very interesting character indeed. Despite his disability he carried on investigating the mystery. I love his service dog, Edison who is loyal and so… smart. Joe Tesla is a software genius. He has a strong personality and will not allow himself to succumb to self-pity whenever he encounters difficulties. This is his most admirable trait. A very likeable hero who saved the world! I am looking forward to books two and three and I hope Ms. Rebecca Cantrell will write book four ASAP. Also please let it be Mr Jeffrey Kafer to continue narrating the series. He is fantastic !
