James and Lucie would spend the days playing on the outskirts of the dark forest, swimming and fishing in the nearby river, and riding horses over the green fields. Sometimes they would try to peep over the wall of the Blackthorn house, but the walls were choked with thorny vines. Razor-tipped briars wrapped around the gates as if Blackthorn Manor had been long abandoned and overgrown, and though they knew that Tatiana Blackthorn lived there, they had only seen her carriage going in and out from a distance, the doors and windows firmly shut.

James had once asked his parents why they never socialized with the woman who lived next door, especially since Tatiana was related to James’s uncles, Gideon and Gabriel Lightwood. Tessa explained diplomatically that there had been bad blood between their families since Tatiana’s father had been cursed and they’d been unable to save him. Her father and her husband had died that day, and her son, Jesse, had died in the years since. She blamed Will and her brothers for her losses. “People become locked in bitterness sometimes,” Tessa said, “and they wish to find someone, anyone, to blame for their grief. It is a shame, for Will and your uncles would have helped her if they could.”

James had not given much more thought to Tatiana: a strange woman who hated his father unreasonably was not someone he wished to know. Then, the summer James turned thirteen years old, a message came from London to tell Will that Edmund and Linette Herondale, James’s grandparents, had died of influenza.

If Will had not been so distracted by his loss, perhaps things would have gone differently.

But he was, and they didn’t.

The night after they learned of Linette’s and Edmund’s deaths, Will had been sitting on the floor in the drawing room, Tessa in the overstuffed armchair behind him, and Lucie and James had been stretched upon the fireplace rug. Will’s back had been against Tessa’s legs as he stared unseeing into the fire. They had all heard the front doors open; Will had looked up when Jem came in, and Jem, in his Silent Brother robes, went over to Will and sat down beside him. He drew Will’s head against his shoulder, and Will held the front of Jem’s robes in his fists and he cried. Tessa bowed her head over both of them, and the three were united in adult grief, a sphere James could not yet touch. It was the first time it had ever occurred to James that his father might cry about anything.

Lucie and James escaped to the kitchen. That was where Tatiana Blackthorn found them—sitting at a table while their cook, Bridget, fed them pudding for dinner—when she arrived to ask James to cut the briars.
