I read the first book when it first came it out and, unfortunately, I didn't get to read the sequels, but I loved it! Double Vision was very interesting and I never really liked reading books about close protagonists with powers at that time, but the book made me change my mind very quickly. I still have my copy and try to reread it any chance I have- it never gets old and I still love it as much as I did my first time reading Double Vision!
