'Cowell's short sentences and scribbly pencil illustrations carry considerable skill and humour, advocate love, and manage to be lively and momentous.'
- Nicolette Jones, The Sunday Times
'Welcome to the fourth and final book in the absolutely sparkling Wizards of Once series... a wonderful series to be savoured by fans of How To Train Your Dragon. It's so well written, the characters and story come totally alive on the page - and Cressida Cowell's beautiful, expressive scratchy drawings add so much. This is mesmerising, truly captivating world-building. The final battle scenes are breathtaking, too - Cressida's imagination knows no bounds, and this is epic stuff! On top of all that, there's real wisdom here about how adults need to take responsibility to sort out the world, which is timely in this era of children protesting against climate change. A great finale to a great series.'
