“It’s done,” Diana said, tossing her duffel bag onto the kitchen island with a clanking sound.
Emma looked up. She’d been over by the window with Cristina, testing the bandages on her hands.
Julian’s healing runes had taken care of most of her injuries, but there were some ichor burns that
were still sore.
Livvy, Dru, and Tavvy were crowded around the kitchen table, fighting over who got the chocolate

outside during the day. They can’t stand sunlight.”
“I wondered,” said Emma. “It didn’t make sense that whoever’s doing this would leave the
convergence unguarded for half the day.”
“You were right to wonder,” Diana said. Her voice was neutral; Emma searched her face in vain
for a clue to whether she was still angry. “During the day the door to the cave seals itself closed. I
watched the entrance disappear when the sun rose. It didn’t interfere with setting up the monitoring
runes and wards—I did that outside the cave—but no one’s going into that convergence while the
