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.

I wish I could rate this camera -9999999999999999999999999999999. Actually what I really wish is to mound all of the Vivitar Vivicam 55 cameras up in a pile and BURN THEM. Anyway, I found this camera at Walmart thinking it should be good for the $20 price tag they were asking. When I first opened this wannabe camera I noticed the buttons were very cheap. More than half the pictures taken were either blurry and/or yellowed. Don't bother trying to create a video with this thing unless you like a still frame video. I brought it back after I did some research and found the Logitech C310 Webcam for several dollars more here on Amazon(which has HD!). This is the worst camera i have EVER used. Live and learn, and never buy anything made by Vivitar. Shop around and spend a few extra dollars for a better camera. If not, you get what you pay for.

The Scarlet Letter is not a dull book if you get into it. It is true that it's language can be hard to read and understand at times, but that does not make it uninteresting. The main story, may not be considered exciting, but the novel is full of literary elements that make it a good book. Several faults are pointed to in this "perfect" Puritain town in which the story takes place. The book uses good elements like foreshadowing, foil characters, and a lot symbolism. A main point of the book is Hester's admiting her guilt as compared to her "lover's" hiding his guilt. I'm not going to tell you who she had the affair with, but it will be soon figuared out when you see the signs of his scarlet letter. The book may not be as exciting as some, but don't let this keep you from reading it, because it really is good.
