A dark and starless forest / Sarah Hollowell.

"Derry and her eight siblings live in an isolated house by the lake, separated from the rest of the world by an eerie and menacing forest. They know it's for their own good. After all, the world isn't safe for people with magic. And Derry feels safe--most of the time. Until the night her eldest sister disappears. When a second sibling goes missing, feeling safe is no longer an option. Derry will risk anything to protect the family she has left. Even if that means returning to the forest that has started calling to Derry in her missing siblings' voices. As Derry spends more time amidst the trees, her magic grows more powerful . . . and so does the darkness inside her, the viciousness she wants to pretend doesn't exist. But saving her siblings from the forest might mean embracing the darkness. And that just might be the most dangerous thing of all."--Dust jacket flap.
