The first entry in the New York Times–bestselling series.
Old Ms. McMartin is definitely dead, and her crumbling Victorian mansion lies vacant. When eleven-year-old Olive and her dippy mathematician parents move in, Olive is right to think there's something odd about the place - not least the strange antique paintings hanging on its walls. But when she finds a pair of old glasses in a dusty drawer, Olive discovers the most peculiar thing yet: she can travel inside these paintings to Elsewhere, a place that's strangely quiet...and eerily familiar. Olive soon finds herself ensnared in a plan darker and more dangerous than she could have imagined, confronting a power that wants to be rid of her by any means necessary. It's up to her to save the house from the shadows, before the lights go out for good.
