I was skeptical when I first saw the trailer for ABC Family’s teen summer series, Pretty Little Liars, back in March. I noted just before the big premiere it looked like a watered down version of suspense-thrillers like “I Know What You Did Last Summer,” and “Sorority Row,” but I was wrong about the show. It’s actually pretty fun to watch.

And I’m not the only one who’s been enjoying it on Tuesday nights. The surprising summer hit has been pulling in excellent ratings for the network, which prompted them to pick up an additional twelve episodes of the series. That means the first season will be a full twenty-two episodes long, with the first ten episodes rounding out near the end of August.

The show will most likely take a mid-season break and come back just in time for winter holiday vacations, when teens have more time to watch television.

My fifteen-year-old is loving this show, and has officially dubbed Tuesday nights her new favorite night of the week…

well, right after Monday, which also features ABC Family favorites, Secret Life of the American Teenager and the brand new summer program, Huge.

Mystery, intrigue, bad behavior… Pretty Little Liars is everything I hope my own teenager never becomes, and entertainment enough for the entire family to sit down together and enjoy some quality TV time.
