Who would buy it not knowing what is on it, is there any new material, is there a better version of music than previously released, how many, etc., etc. You've got to tell us something - give us a reason to buy it - give us a few short pieces to listen too! King indeed; he's pretty good but the King has been dead awhile (notwithstanding the occasional phantom sighting) and the remaining living creators of original rock and roll - Jerry Lee Lewis and Chuck Berry are very much alive and touring and in Jerry Lee's case still recording great music.I'll take a look at buying this if I can see and hear what it is!Jimp.s. sorry for the 1 star but ...

I came up to this book (a reading assignment for school) with a bit of dread, having heard that Hawthorne's writing could be hard to read. Actually, it was a delightful suprise to find it was a captivating plot, very well written, and very easy to read. I enjoyed it thoroughly. This book is about a woman who has an affair, choosing to bear the scarlet letter than reveal her lover's identity. Along side her is her ilegitamate daughter, a delightfully and hillariously strange character in the book. The scarlet letter is a good book having a melancholy but redeeming ending. A definate classic. Check it out... it'll be better than you expected.

I find this book highly useful as a desktop reference for just about anything HTML/DHTML related. In addition, Powell does a great job of introducing topics that may be new to some people, like XML.
