This snippet is from the fifth Mortal Instruments book, City of Lost Souls. This is after Jace becomes evil, and Cassie ended up rewriting this scene for the book, but this was the first draft.
Clary didn’t know how long she’d been sitting on Luke’s front steps when the sun began to come up. It rose behind his house, the sky turning a dark pinkish-rose, the river a strip of steely blue. She was shivering — had been shivering so long that her whole body seemed to have contracted into a single hard shudder of cold. She had used two warming runes, but they hadn’t helped; she had a feeling the shivering was psychological as much as anything else. Would he come? If he was still as much Jace inside as she thought he was, he would; when he said he would come back for her, he would have meant as soon as possible. Jace was impatient. And he didn’t play games.
