Review quote

Part book, part comic, this book is fast, furious fun * TheGuardian.com * 'The tale is told with panache and a cracking pace. It fizzes with excitement' * The School Librarian * '... this book is perfect for reluctant readers, because the scenes that build tension, and the scenes of superhero action are all depicted by Cathy Brett as graphic comic strips... The next in the series is out on 1 August this year and I'm feeling tingly already.' * MinervaReads * 'Original, clever, and smartly written...' * Teach Primary * 'A delight from start to finish for younger readers' * Cotswold Preview * '...an exciting sci-fi adventure narrative' * The BookTrust * 'Brett's drawings are distinctive, original and should draw in any eight-year-old; Cotterill's language is straightforward without appearing patronising.' * Alex O'Connell, The Times Saturday Review * 'A great fun read for anyone age 9+' * Midweek Mercury * 'an innovative approach to the superhero story ... exciting and told with a touch of humour' * Anne Thompson, TheBookBag *show more
