[EX Q]: 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.
[EX A]: Negative

[EX Q]: So it was long, and it was a slow read, big DEAL. Ms Lackey and cohorts have spun a gripping, involved tale of GREAT characters, involved PLOTTING and lots of FUN. I read for pleasure and this was a pleasure. I was always looking back to keep things straight, but it was FUN. I lost most of two nights sleep because I couldn't put it down. This team should write lots of sequels, and I WILL BUY THEM ALL.Be warned, if you pick up this book and start reading you will suffer. Yours friends and family will think you have run away, and you have, To Venice, where you can spend a ripping vacation in you mind. The lady has won me back.
[EX A]: Positive

[EX Q]: Nice in theory, but doesn't really do the trick. We thought the longer shaft and small profile would make it easy to hold it in the right spot during intercourse to give me the extra zing necessary. The problem is, the surface is difficult to press up against the right spot. If the paddle had a nub on it or it was convex would make it a lot better.I was also disappointed in the speed/strength. In order to turn it on, you have to twist the base. The problem is, it goes from zero to full strength. No gradual increase. The strength is a little much to start off, and usually not enough after a short while. It would be nice if the power were adjustable.Positive: Very easy to clean - waterproof - inexpensive - slender design makes it easy to bring with you anywhere.
