'This book is like sitting beside a giddy 10-and-a-half-year old – it positively fizzes with things that it wants to tell you, right this very minute.' Irish Examiner

'A delightful new heroine for kids who just can't help causing havoc.' Sarah Breen

But from the moment Milly and her friends arrive, chaos and calamity ensue – and of course, Milly is totally not to blame for the butterfly breakout, the giraffe drama or the unfortunate incident on Monkey Island …

Could the school lose their Green Flag before it even arrives?
