The Dark Unwinding by Sharon Cameron
Scholastic, September 2012
Katharine Tulman is an orphan whose survival depends on her ability to figure accounts for her aunt. Hearing that her uncle may be squandering her cousin's inheritance, Katharine is sent to his estate to declare him insane and have him committed. But what she finds is a childlike man with a genius for creating clockwork and an entire village rescued from the poorhouses who support him. Katharine must choose between her future and that of the village, and on the estate, she's experiencing the first days of freedom she's ever known. Madness and mystery, fortunes and romance, The Dark Unwinding is the fantastic result of mixing clockwork and Jane Eyre-- steampunk fans will cry for more.
