The Tipping Point by Malcome Gladwell.
-This is a work of nonfiction analyzing how and why certain things "tip". An example of something tipping would be the drastic drop in crime in NY during the mid-90s. The author explains the different key people/things very well and keeps your attention easily. It's also a quick and easy read. And I have to read it for AP World Geo. so joy =/
But read that if you're interested in the sociology of pop occurances (ignore all the spelling mistakes that have just happened
)
that is moses's reccomendation for the howeverlong it seems fit.
