The Secret History | Donna Tartt

Under the influence of their charismatic classics professor, a group of clever, eccentric misfits at an elite New England college discover a way of thinking and living that is a world away from the humdrum existence of their contemporaries. But when they go beyond the boundaries of morality, their lives are changed profoundly and for ever.
 

The Secret History is a story of two parts; the chain of events that led to the death of a classmate—and what happened next.
