Nicely done. I rather enjoyed some of the 'rush to the finish' feel--all too often in stories like this I feel that Harry sits and twiddles far too long, just to wait until his 7th year to off Voldie. I'm glad you didn't do that, but had Harry go right to work, using his foreknowledge of events and circumstances.
And, I didn't find it terribly cliche-ridden, either. :)
Yet another excellent effort from you, and I look forward to reading more of your works in the very near future.
