“The Ninth House has a secret, Nav,” said Harrow. She sounded calm and measured and frank in a way she’d never been before. “Only my family knows of it. And even we could never discuss it, unless—this was my mother’s rule—we were immersed in salt water. We kept a ceremonial pool for the purpose, hidden from the rest of the House. It was cold and deep and I hated every moment I was in it. But my mother is dead, and I find now that—if I really am to betray my family’s most sacred trust—I am obliged at the least to keep, intact, her rule.”
