The main bulk of the book is Bon Jovi (I'd say around 40%). It's well worth reading even if there was no jovi in it. A good view of what life is really like on the road with some of the worlds biggest acts.

There's stuff in there that would never had heard about - Tico stealing Bubbles the chimp, suspected snipers in the crowd, the zuccini twins, the lost weekend... Great stuff.
