Thanks to COVID-19, JK Rowling rediscovered an unfinished tale that she had written for her own children ten years ago "in fits and starts" between the seven Harry Potter books. During lockdown she put it online for free, inviting the millions of children stuck at home around the world to contribute illustrations. Now, and in our darkest hour, it is published; and just like Harry Potter, it is a light for when other lights go out....
The winning illustrations by children of 7-11 from Australia, New Zealand, India, Ireland and Britain are a delightful touch, and royalties are donated to the Volant Charitable Trust to assist groups particularly hurt by Covid-19. Rowling has written some entertaining novels for adults, but it is as a children's writer that she has achieved phenomenal world-wide fame. The Ickabog won't just be put under every lucky child's Christmas tree: it is a monster hit that deserves to be.
