Read the first three parts of chapter one of City of Lost Souls:
“Hey.” A slim figure stepped into the room and shut the door. Alec, Isabelle’s older brother, was dressed in Council wear—a black robe figured with silver runes, open now over jeans and a long-sleeved black T-shirt. All the black made his pale skin look paler, his crystal-blue eyes bluer. His hair was black and straight like his sister’s, but shorter, cut just above his jawline. His mouth was set in a thin line.
Clary’s heart started to pound. Alec didn’t look happy. Whatever the news was, it couldn’t be good.
