This is an exclusive, signed hardback edition of Half Bad by Sally Green: the breathtaking debut novel about one boy's struggle for survival in a hidden society of witches.

You can't read, can't write, but you heal fast, even for a witch.

You get sick if you stay indoors after dark. You hate White Witches but love Annalise, who is one.

You've been kept in a cage since you were fourteen. All you've got to do is escape and find Mercury, the Black Witch who eats boys. And do that before your seventeenth birthday. Easy. "A book about witches with no owls and not a pair of round spectacles in sight.

The new Hunger Games, I suspect...Brilliant and utterly compelling - I loved it". (Kate Atkinson, author of Life after Life and Behind the Scenes of the Museum). "Teens rejoice: the inheritor to Stephenie Meyer's crown has arrived". (Fiona Wilson, The Times). "Edgy, arresting and brilliantly written, Half Bad grips you from the first page and doesn't let go". (Michael Grant, author of Gone). "A brilliant debut that is both deeply unique and unsettling, one that chilled me to the bone and broke my heart even as I sped through its pages.

This will haunt you". (Marie Lu, author of Legend). "Take our word for it, this book is going to be huge". (Stylist). "Brilliantly paced with more than a few nasty surprises, Half Bad is a wickedly addictive read that will capture the imagination of any fan of YA fiction". (Starburst). "Not since the Harry Potter books - yes, I said it! - have I felt so fully immersed in an author's creation...I couldn't be more stoked over Half Bad, and this launch novel of a trilogy truly deserves all the hype surrounding it - and much more..." (Amanda Hurley, Inkwood Books).

Sally Green lives in north-west England. She has had jobs (paid and unpaid) and even a profession but at last has found the time to write down the stories she used to only be able to daydream about.

She likes to read, walk in the country and would like to drink less coffee.

Half Bad is her first novel.
