Pretty little liars.

This is my favorite series the whole world. It develops in America and the plot is four girls are treating to find to their friend Alison because she has disappeared. Moreover, they have a "stalker" whose name is -A. He always send them messages saying things like: you're idiots, bitches. -A. This series have five seasons right now, but it will be seven. This is my favorite series because there is love, mystery, friendship and murder. They are Aria, Spencer, Hanna (my favorite) and Emily.

BEST SERIES EVER.
