Even that single star is more than this book is worth. My Engligh professor assigned this book to me during my sophomore year of college (along with Nectar in a Sieve, a far better, though not terrific book), and what little I remember of it was that it was just awful (and offal). Her writing is repetitive and choppy, perhaps descriptive but disgustingly so. Do we really need to know the "wetness between [her] legs", or that she cooked her menstrual fluid into some poor soul's dinner? I couldn't stand the book. If you want quality, read something by Neil Gaiman, or Stephen King (his descriptions of a girl coming of age in Carrie are much better than this book). Drop the book, throw it, burn it, whatever. It's just not worth reading. How many trees did we lose to its production (and, more importantly, how many talented young writers were rejected because this woman was published). It's just a book not worth reading about a story not worth telling.

not bad but be warned you need to buy extra play-doh at local store before handing it to the kid's

This was by far the worst science fiction novel I have ever watched. While the story of two lovers may seem romantic to some people, the use of spaceships and alien robots was very unneccesairy. The worst part of this play had to be the end where both charaters joined up with Marty McFly to save the universe. Thumbs down to you sir! The remix WAS better.

Negative
