As we've previously reported, Pretty Little Liars showrunner Marlene King is writing the screenplay for City of Bones, the first book in the hit supernatural YA series The Mortal Instruments, by Cassandra Clare.

Marlene King gave MTV's Hollywood Crush more details about her work on the project. She explained that she's not actually writing the script from scratch. Rather, she's "rewriting" the script they already have. She's also been reaching out to author Cassandra Clare when she has questions, and says Cassandra has "been very collaborative and wonderful."

So what scene from the book was Marlene most excited about working on? "The Jace-and-Clary-in-the-greenhouse scene," she explained. "It's very romantic and really fun."

If there's one thing Marlene does well, it's turning romantic and fun books into fantastic screenplays.  We're sure she'll rock this scene and the whole script.
