I just read Brit volume 1, another book set in the Invincible universe. This one wasn't as enjoyable for me as the other material, but it was from very early on in the piece, so things were still falling into place creatively. It wasn't bad by any means, it just didn't excite me like the other Invincible universe stuff I've read. I have ordered volume 2 though, I intend to see the series through. Art by Tony Moore, and nice colours by the nicest guy in comics, Val Staples.
The tpb contains 3 'books'. A book is roughly 46 pages each, so a tpb does contain the same as a regular 6 issue tpb, actually a bit more as there's also a 7 page epilogue and sketchbook. So that's 3 more to my total, taking me to 115 for the year to date.
