Pretty Little Liars by Sara Shepard [COMPLETE 16 BOOKS] [EPUB]

Pretty Little Liars is a series of young-adult novels by author Sara Shepard, beginning with 2006's initial novel of the same name. The series follows the lives of four girls – Spencer Hastings, Hanna Marin, Aria Montgomery, and Emily Fields – whose clique falls apart after the disappearance of their leader, Alison DiLaurentis, in the summer after 7th grade. Later, when the girls are juniors in high school, they begin receiving various messages from someone using the alias "A" who threatens to expose their secrets.

The novels explore several different topics and themes such as bullying, murder, drug addiction, underage drinking, eating disorders, homosexuality, peer-pressure, infidelity, and mental illness. Moral ambiguity and the consequences of lying (suggested by the title) are featured prominently in the series; the girls constantly create their own problems through their unwillingness or inability to tell the truth about certain events and misdeeds they have done.
