T.K Roxburgh is a local writer I have recently discovered, thanks to a tip from a friend and a full page spread in the ODT recently.
She has written a sequel to Shakespere's MacBeth, titled Banquo's Son, which was picked up by Penguin. It will be available in stores on the 1st of October $37NZ. The trilogy and film rights are about to be auctioned in America.
The book, set in Scotland in 1100AD, looks awesome; I can't wait to get my sticky little hands on a copy.
You can find her blog at www.banquosson.blogspot.com, a candid and enjoyable read about writing and her journey to get these books published. You can find a list of her YA books here as well.
