Becky Sharp is the heroine of which famous novel?

Rebecca or Becky Sharp is the main character of William Makepeace Thackeray's satirical novel Vanity Fair (1847–48).

A cynical social climber who uses her charms to fascinate and seduce upper-class men, Sharp is contrasted with the clinging, dependent Amelia Sedley. She befriends Amelia at an expensive girls school where Becky is given a place because her father gave their drawing lessons and she helps the younger girls with their French. Becky then uses Amelia as a stepping stone to gain social position.

Sharp functions as a picara—a picaresque heroine—or by being a social outsider who is able to expose the manners of the upper gentry to ridicule.
