A pretty rudimentary taste before the movie comes out.
The tribute medallions are cool, as are the few pictures. It's like a super mini summary of HG #1 right up until Katniss emerges out of the tube into the arena.
If you're looking for a super detailed look into HG, it's not here. As for it being a 'tribute guide', it really is just a head shot of all 24, plus age, height, district of origin, and if their name is mentioned in the book, that as well. If not, no name is given.
I could complain about that, but these are brutal books, and the less you know about the 16-18 tributes that die pretty quickly, the better.
