Ravenswood casts two leads

Brett Dier (L.A. Complex) and model Elizabeth Whitson have been cast for Ravenswood, the Pretty Little Liars spin-off. Last week ABC Family already announced that Tyler Blackburn will leave Rosewood to play a lead in Ravenswood.

Dier will play Abel, a lone wolf and old soul with a brooding intensity. There's something dangerous lurking inside him, or he could be wounded and covering. His trust is hard won but once you're in his inner circle, he'll never let you down.

Whitson will play Olivia. Abel's twin sister and a former prom queen who has fallen from grace who's learning who her real friends are after most everyone in her inner circle turns their backs on her. Recent events have left the once carefree and effortlessly happy Olivia questioning what's important to her.

They will both be introduced in Pretty Little Liars' Halloween episode.
