ABC Family would pair "Pretty Little Liars" and "Greek" in January next year starting date 3 with the former leading at 8/7c. This would be "Liars" mid-season debut after the successful 10 episodes over the summer while it would be "Greek" 's fourth and last season.

The cable network has released several details which may contain spoilers to the new chapters. On "Pretty Little Liars", the mystery and ominous messages continue for best friends Emily Fields, Spencer Hastings, Hanna Marin and Aria Montgomery. No longer just threatening to reveal secrets, the all-knowing "A" has stepped up the game and nothing is off limits in the second half of the first season.

And while they work hard to protect what they know, the four girls are also on the hunt to learn the truth about what happened to Alison the night she disappeared. But when those truths start to come out, will the Liars be prepared for what they must face when new secrets are revealed?

On "Greek", the storylines turn to the post-graduation experience for Casey, Ashleigh and Evan, while the undergrads must continue to deal with life on campus. Die-hard fans will be treated to throw-back references from past seasons.

On related news of "Liars", E! has just revealed that Lindsay Shaw from "10 Things I Hate About You" series would be in two episodes as Paige McCullers. She is one of the swimmers in Emily's team and is a competitive one. Last week Alona Tal and Tyler Blackburn have been announced as two characters which can't be found in the book versions. In respective order they would play Simone and Caleb.
