Shadows n Secrecy

“Shadowhunters,” he said. “They get in your blood, under your skin. I’ve been with vampires, werewolves, faeries, warlocks like me—and humans, so many fragile humans. But I always told myself I wouldn’t give my heart to a Shadowhunter. I’ve so nearly loved them, been charmed by them—generations of them, sometimes: Edmund and Will and James and Lucie . . . the ones I saved and the ones I couldn’t.” His voice choked off for a second, and Luke, staring in amazement, realized that this was the most of Magnus Bane’s real, true emotions that he had ever seen. “And Clary, too, I loved, for I watched her grow up. But I’ve never been in love with a Shadowhunter, not until Alec. For they have the blood of angels in them, and the love of angels is a high and holy thing.”

“Not forever, Tessa thought. They had a long, long time. A lifetime. His lifetime. And she would lose him one day, as she had lost Will, and her heart would break, as it had broken before. And she would put herself back together and go on, because the memory of having had Jem would be better than never having had him at all.”

“This boy, hell-bent on fighting rather than finding a family. The Lightwoods guarding against a vampire, when they could have extended some trust. This vampire, holding every friend at bay. All of them had their wounds, but Brother Zachariah could not help resenting them, for even the privilege of feeling hurt.

All these people were struggling not to feel, trying to freeze their hearts inside their chests until the cold fractured and broke them. While Jem would have given every cold tomorrow he had for one more day with a warm heart, to love them as he once had.”

“Jordan leaned on the counter. He felt a little like a bartender in a TV show, dispensing sage advice. "What do you owe her?"

"Life," Isabelle said.

Jordan blinked. This was a little beyond his bartending and advice-offering skills. "She saved your life?"

"She saved Jace's life. She could have had anything from the Angel Raziel, and she saved my brother. I've only ever trusted a few people in my life. Really trusted. My mother, Alec, Jace, and Max. I lost one of them already. Clary's the only reason I didn't lose another.”
