Are you looking for stories like Liar's Poker, or like investment books, or both?
In the story category, some a little heavier than Liar's Poker:
Monkey Business (basically a b*tch fest about investment banking)
Barbarians at the Gate
Predator's Ball
When Genuis Failed
Den of Thieves
Snowball (haven't read yet)
Money Culture (another Lewis book)
Greed and Glory on Wall Street
Memos from the Chairman (very funny)
Hedgehogging
The Vulture Investors
Fooling some of the people all the Time
Actually, if you want some entertaining and very readable books (some of the above are dry but informative), check out the 2 by Andy Kessler, true insider accounts from the buyside and the sellside--Wall Street Meat and Running Money. He's one of the few guys who writes kind of like Lewis.
Some investing books I would recommend:
Intelligent Investor (the bible)
The Essays of Warren Buffet
Beating the Street
One Up on Wall Street
Margin of Safety (if you can find a copy, maybe the library)
Investment Biker
Fooled by Randomness (not just for investing, must read in general)
You can be a stock market genius (corny title, great book)
The Little Book that Beats the Market (quick easy read)
Aggressive Conservative Investor
And I'd second KOAJs recommendation.
That should keep you busy for a while.
