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 Output:
Positive

This book is a very informative, yet easy read about the realities of life and how patterns are repeated sometimes even unknowingly until honestly addressed and changed. That is where the power of this book lies in giving insight, tools, all with a touch of humor to make positive changes of direction in our lives. Highly recommend.

Horrible product! Too much talking about general stuff. Not enough real tests. Very low level of expertise. it is just ridiculous how people can get published with such book about nothing. Bits and pieces here and there. Please, Amazon, do not sell this book - too little of material for too much money. It's a SHAME!!!!!!!!!
