It was, but I can't seem to ever remember how it ended.
Nicholas Pellegi's "Wiseguys" was an interesting read.
The book was great too.
It ended like this, Henry and Jimmy were in a diner, Jimmy asked Henry to go to Florida to do a hit for him, Henry realized it was a set-up, he and Karen talk to Ed McDonald (who was the real life prosecutor in the case, they were testing actors to play Ed but he played himself better LOL) then we see the Court scene where all the players are on trial, then Henry leaps out of the witness stand, talks about the life and says this (courtesy of IMDB)
Henry Hill: [narrating] Anything I wanted was a phone call away. Free cars. The keys to a dozen hideout flats all over the city. I bet twenty, thirty grand over a weekend and then I'd either blow the winnings in a week or go to the sharks to pay back the bookies.
[Henry leaves the witness stand and speaks directly to the camera]
Henry Hill: Didn't matter. It didn't mean anything. When I was broke, I'd go out and rob some more. We ran everything. We paid off cops. We paid off lawyers. We paid off judges. Everybody had their hands out. Everything was for the taking. And now it's all over.
[narrating]
Henry Hill: And that's the hardest part. Today everything is different; there's no action... have to wait around like everyone else. Can't even get decent food - right after I got here, I ordered some spaghetti with marinara sauce, and I got egg noodles and ketchup. I'm an average nobody... get to live the rest of my life like a schnook.
Then you see him coming out the front door of his house with not much around, in his robe, and he smirks.
I'm a mob movie fanatic LOL.
