In the middle of a deadly bog sits the House of Quiet. It's a place for children whose Procedure triggered powers too terrible to be lived with--their last hope for treatment. No one knows how they're healed or where they go afterward. Birdie has begged, bargained, and blackmailed her way inside as a maid, determined to find her missing sister, Magpie.

And with fellow maid Minnow keeping tabs on everything Birdie does, danger is everywhere. In her desperate search for Magpie, Birdie unearths terrifying threats and devastating truths, forcing her to confront just how much she's willing to sacrifice to save her own sister. Because in the House of Quiet, if you find what's lurking beneath . . . you lose everything. Unravel the mystery. Ignite the rebellion.
