The Game by Neil Strauss

Nearly every major city in the world has them: hidden underground seduction lairs where men gather to trade the most devastatingly effective techniques ever invented to seduce women.
This is not fiction.
For two years, bestselling author Neil Strauss lived among these men. Using the pseudonym Style to protect his real-life identity, he began his remarkable journey from AFC (Average Frustrated Chump) to PUA (Pickup Artist) to PUG (Pickup Guru) -refining his approach, sharing unforgettable encounters with the likes of Tom Cruise, Britney Spears, Paris Hilton, and Courtney Love, and ultimately transforming himself from frog to prince . . . to prisoner.
And then things started to get really strange.
One of the most explosive and controversial books in years, The Game is guaranteed to change the lives of men and transform the way women understand the opposite sex forever.
