So, I just finished reading Trading With The Enemy: Seduction and Betrayal on Jim Cramer's Wall Street by Nick Maier. The book is basically a narrative talking about a young inexperienced guy (the author) who, seduced by the money on Wall Street, ends up landing a job with the now-famous Jim Cramer. At the time, Cramer was a big-time hedge fund manager. Anyway, the book goes into detail about what it was like dealing with Cramer on a day-to-day basis as one of his people. There's nothing particularly insightful about the book, but if you've ever seen Cramer on his CNBC show titled Mad Money and enjoyed it for any reason, you might find the book entertaining; I know I did.
If you liked Liar's Poker or Monkey Business, you might find some enjoyment out of the book. At the very least, it's an incredibly fast read, so if you end up hating it, you would not have wasted much time.
Bottom Line is... there's greed and megalomania, and then there's Cramer.
