A classic overachiever, Spencer Hastings balances school, a high-powered internship, charity work, the field hockey team and maintaining uber-popularity status -- all without breaking a sweat. This is the girl who could stand up to Alison when no one else would. But when she and her friends begin receiving mysterious messages from "A," even the calm, cool and collected Spencer starts to show a little strain. And when she develops a forbidden crush on her sister's fiancé you have to wonder if Spencer can keep it together.
