Cogheart

Lily's father has vanished, and now men with silver eyes are following her through the dark. Why they want her, and how much danger she is really in, are questions she must answer quickly.

Lily is not left to face this alone. She teams up with Robert, a clockmaker's son, and Malkin, her mechanical fox. Together they are pulled into a shadowy and hostile underworld where nothing is quite what it seems. As they dig deeper, Lily begins to fear that the people closest to her may be the ones who will hurt her most.

The story combines violence, confusion and a tangle of puzzles in a steampunk-inflected Victorian setting, written for middle-grade readers.
