While this is definitely science fiction, it doesn't necessarily read like it at first. Considering how far medical science has come since the 1970s and the television program The Six Million Dollar Man, some of Mira's bionics are completely realistic. As the book progresses, we do leave the realm of what is currently available, but will this book still be science fiction in 30 more years? I loved that the bionics were essentially good, even though the levels needed to be tweaked a bit. Maybe I'm old enough to equate science with advances in civilization instead of dystopia, but this was so much more enjoyable than viruses infecting the world or some other scenario where EVERYTHING goes bad. Even though Mira is a high school senior, this is still completely appropriate for middle school. I was on edge for a lot of the book, however, just waiting for something inappropriate. This is exactly what some of my more mature 8th grade readers want. Middle school students definitely enjoy reading about high school characters.This is a great sci fi title for readers who don't think they like sci fi. I can see people who liked Uglies really enjoying this. And it involved BIONICS. What's not to like? A great, quick read.
