Best 8th Level Adventures?

[RexInvictus]

What would you guys say are the best 8th level (or higher, I'm willing to take higher) adventures?

My party's switched over to a semi-evil campaign and I'm looking to take some typical adventures, change the goals slightly so that they fit more villainous intent and use them wholesale.

I looooove the Harrowing. It's a 9th level 32-page module that basically brings the Harrow deck to life, so you're fighting and interacting with all kinds of crazy stuff. And you have lots of opportunities to make deals with evil stuff.
