The Sisters Grimm (Broché)

They found each other at eight, were separated at thirteen. Now they are nearly eighteen and must find each other again... This is the story of four sisters Grimm — daughters born to different mothers on the same day. Each born out of bright-white wishing and black-edged desire. In thirty-three days, the sisters will meet - their father in a place they go to when they dream. Only then will they discover who they truly are.
And what they can truly do. Then they will fight to save their lives and the lives of the ones they love.
