Clara Woods is a killer--and perfectly fine with it, too. So what if she takes a couple of lives to make her own a little bit better? At the bottom of her garden is a flower bed, long overgrown, where her late husband rests in peace--or so she's always thought.

Then the girls arrive.

Lily and Violet are her nieces, recently orphaned after their affluent parents died on an ill-fated anniversary trip. In accordance with their parents' will, the sisters are to go to their closest relative--who happens to be Clara. Despite having no interest in children, Clara agrees to take them, hoping to get her hands on some of the girls' assets--not only to bolster her dwindling fortune but also to establish what she hopes will be her legacy: a line of diamond jewelry.

There's only one problem. Violet can see the dead man at the bottom of the garden. She can see all of Clara's ghosts . . . and call them back into existence. Soon Clara is plagued by her victims and at war with the gifted girls in her care. Lily and Violet have become a liability--and they know far more than they should.
