I'm astonished at how much I loved this book. I got sucked in from the get go and raced through it to see how the story could possibly get solved (spoiler alert it's in the first of a series). I also couldn't believe that Hollywood actor, Jason Segel, wrote this. How cool! Apparently he's also written other books as well! This book is like Ready Player One and Westworld if it had been written for teenagers. There is a new virtual reality called Otherworld and it's just been released on the market to 2,000 lucky beta testers. Simon and his best friend (and romantic interest) Kat, get to be some of the lucky first few to experience it. Real life is so boring is boring compared to realness and power of Otherworld. But when Simon discovers that this may be more than a game and it has the potential to kill certain players during the testing phase, he is determined to go back in there and save Kat (who at this point, is being forced to stay in the Otherworld against her will). Engrossing, funny, imaginative, and surprisingly believable; this book will garner teen fans and quite a few adults too. I can't wait for the next one!
