She-Hulk Vol.2, "Superhuman Law," should be out today in book and comic stores. This contains issues #7-12, which feature the awesome arc that was widely discussed here and elsewhere.
To summarize: She-Hulk is transported to an alien planet to adjudicate some of their cases. The planet is currently run by Champion of the Universe, a crappy Marvel villain who has come into posession of the Infinity Gem of Power, rendering him invincible. She-Hulk takes him on anyway, and loses - but then she remembers that as She-Hulk, she's exponentially stronger than she is as Jen Walters.

So she asks for a rematch in three months. Over that time, she goes on an intensive workout regimen as Jen Walters, going from unathletic to fairly buff. Now when she transforms into She-Hulk, she's twice as muscular and many times stronger.

She-Hulk returns to earth, and has trouble dealing with her new size (stomping through the office she causes a mini-earthquake, for example), and the rest of the story I'll leave unspoiled.
Oh, the best part of this - in issue #9, Paul Pelletier becomes artist and takes a less cartoony approach to the subject. His She-Hulk looks incredible. Here she is pre-bulk up.

Here she is post-bulk up.

Pelletier's art is stunning, and when he gets to draw Titania - well, watch the hell out.
If you've missed these issues, buy this book.
