Redoing it Voldemort Style

Fanfiction has sent nearly everyone back to 'fix' things except for the Dark Lord. So this is very AU and the 'fates' or whoever decide that Tom should have a try at it. To Voldemort's dismay he must try to save both the wizarding world and the muggle one as well. Don't really know what pairings I'll try for this time, the characters will likely let me know.
