Cassandra Clare posted a new snippet from City of Heavenly Fire on her tumblr:
Idris had been green and gold and russet in the autumn, when Clary had first been there. It had a stark grandeur in the winter: the mountains rose in the distance, capped white with snow, and the trees along the side of the road that led back to Alicante from the lake were stripped bare, their leafless branches making lace-like patterns against the bright sky.
Sometimes Jace would slow the horse to point out the manor houses of the richer Shadowhunter families, hidden from the road when the trees were full but revealed now. She felt his shoulders tense as they passed one that nearly melded with the forest around it: it had clearly been burned and rebuilt. Some of the stones still bore the black marks of smoke and fire. “The Blackthorn manor,” he said. “Which means that around this bend in the road is …” He paused as Wayfarer summited a small hill, and reined him in so they could look down to where the road split in two. One direction led back toward Alicante — Clary could see the demon towers in the distance — while the other curled down toward a large building of mellow golden stone, surrounded by a low wall. “ … the Herondale manor,” Jace finished.
The wind picked up; icy, it ruffled Jace’s hair. Clary had her hood up, but he was bare-headed and bare-handed, having said he hated wearing gloves when horseback riding. He liked to feel the reins in his hands. “Did you want to go and look at it?” she asked.
His breath came out in a white cloud. “I’m not sure.”
