This book falls into the category where you just WISH they'd make a movie out of it even though it probably would be lousy because the scenes wouldn't match up exactly with what's in your head.
At any rate, Secret History is a lengthy thriller about a group of friends who attend a small college in Vermont and wind up murdering someone within their circle (I promise I'm not ruining anything, you find out who dies on the very first page). All of them are incredibly intelligent and highly interested in Classics. One night, they partake in a crazy Dionysian ritual and things just go downhill from there...Let's just say that people with big mouths are silenced in more ways than one.
Though there was an awful lot of "academic" talk spread throughout the novel (think classics and ancient Greek philosophy), Tartt still manages to create a taut and suspenseful read. Some readers might object to the rampant drug and alcohol use, but it actually helps to capture the paranoid and chaotic mood.
