Coming fall 2013, a new ABC Family drama called "Ravenswood." The series is supposed to be a spin-off from "Pretty Little Liars," but the connection is unknown as of yet.
"Ravenswood" will center on a town, not far from Rosewood, PA (the home base of "Pretty Little Liars"), which has suffered under a deadly curse for generations. Five strangers suddenly find themselves connected by this fatal curse and need to dig into the town's mysterious and terrible history before it's too late for each of them.
PLL's Caleb (Tyler Blackburn) is the only character we know of that will be making the move to Ravenswood. Apparently, some PLL characters will also make appearances there:
