We're riveted by the drama in Pretty Little Liars Season 4, but we haven't forgotten about the upcoming spin-off called Ravenswood, either. We want to know all about Pretty Little Liars' upcoming sister show?

So, what's the deal with this new show? We've gathered the most interesting spoilers about it right here.

Same producers: Pretty Little Liars executive producers Marlene King, Oliver Goldstick, Joseph Dougherty, and Leslie Morgenstein will bring their vision to this new show. But don't worry: They're still making Pretty Little Liars their number one priority.

It's about Ravenswood: Obviously, the show centers on Ravenswood, the creepy, stuck-in-the-past town we were introduced to in Pretty Little Liars Season 4, Episode 6. You can see even more of the town with these set photos.

There's a curse involved: The press release about the show hints that it will have a supernatural bent, as Ravenswood "has suffered under a deadly curse for generations." The plot of the show will focus on "five strangers" who "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." We're guessing this clue photo of a parchment saying "in every generation" is linked to the curse. But what about the hint that "silence is deadly"? Or the chill?

Also, for those of you who are worried: the writers promise that the supernatural is only involved in Ravenswood. It won't spill over into Pretty Little Liars.

Caleb will be there. There will be one familiar face at the center of this show: Caleb (Tyler Blackburn), who will turn out to be connected to the town; Marlene King says she has "big plans" for him on the show. Why Caleb? That should become clear once we know more about the town. What does that mean for Haleb? It's still unclear.

Meet the cast. We've been introduced to a number of cast members of the new show. You can learn all about them here.

Look for a connection this Halloween: Ravenswood premieres on ABC Family after Pretty Little Liars' annual Halloween episode, and PLLwriter Lijah Barasz tweeted that the Halloween episode "will intro the world to #Ravenswood," including several of the main characters.

Someone's missing: Based on this clue photo, someone is "missing" in Ravenswood. We're already intrigued.

The stakes are very high. Higher than on Pretty Little Liars, even.
