EXCLUSIVE: Fox 2000 has acquired film rights to Sally Green’s debut book Half Bad, a contemporary supernatural thriller. The film will be produced by Karen Rosenfelt, whose recent films include Twilight Saga, Percy Jackson: Sea Of Monsters, and The Book Thief. Half Bad starts a trilogy taking place in a world inhabited by covert witches; one faction is good and the other evil. They are divided by hatred and united by one thing only — fear of a boy descended from both sides. The YA title will be published under the Penguin imprint in spring 2014. The book was a hot title at Bologna Children’s Book Fair, and since then, Zosia Knopp, Penguin Children’s Rights Director, concluded a six-figure U.S. rights deal at auction, along with Ken Wright, VP and Publisher of Viking, an imprint of Penguin Young Readers Group. Pre-empts have been accepted from Brazilian publisher Intrinseca and Israeli publisher Kinneret. Multiple offers have been received from Germany (eight houses bidding in Puffin’s biggest German auction to date), France (five offers on the table), Italy (four offers), the Netherlands and Serbia.

The film deal was brokered by Claire Wilson of Rogers, Coleridge and White Ltd and CAA.
