Having just finished the advanced copy myself, I agree that it is definitely a good, old-fashioned team story. This shows a group of four people who are more than just a team. They are a family that care about each other. That was a strong emotion and story catalyst in the early years of the show (known online as the "classic years"), and it felt good to see it again in this book.
They worked together to get out of their misadventure, each using their particular field of expertise in a logical manner and performing tasks in-character. There was adventure, angst, fighting, whumping, moments of extraordinary friendship -- everyone had a very strong role in this tale.
All in all, it "felt" and "read" like a classic year story, and that's pretty high praise in my humble opinion.
