Oh boy, where to begin. For starters, this book is not for adults. I'd say it's more for the age range of 14-22 year olds as the last half of the novel is mostly geared towards a child playing with his "Good Buddy" doll, except this one isn't as evil. There's so many things wrong with this book that I can't list them all, and it's a real shame because I was a fan of Preston but lately his books have turned far too predicable, as with others in this genre, like James Patterson and Preston's buddy Lincoln Child for example. I have to admit that I did like the overall premise of this story but it was so flat and Preston feels the need to prod the reader with useless pop-culture references, including one of his buddy's own novels. Yes, he mentions "The Third Gate" by Lincoln Child. It was sad. I just rolled my eyes when I read that and put the book down. Oh, I forgot to mention that one of the FBI agents has to have it explained to him why the A.I. program is named "Dorothy". The first thing that popped into my mind was the movie 'The Wizard of Oz'. After that's explained to him he doesn't even know who Judy Garland is. I almost tossed the book across the room after reading that part. I would have LOVED to have read the A.I. program's journey on Saturn's moon Titan but instead we get people chasing down a program's journey though the internet and then the same people looking for a boy and his "robot".... ooooo, how thrilling! Anyway, this advanced copy was free and I'm glad because it's the worst book of his I've ever read... and I'm not to keen on reading anymore of his now sadly.
