Two brothers, one serum, and a world of trouble!

Praise for SWITCH This book has helped my son, 5, move on from picture books at bed time to one with more words. An excellent choice for reluctant readers who will be thrilled at the idea of turning into a bug, mad inventors and lots of adventures. Amazon Reviewer The book is great fun and involves the reader, who really feels as though they are part of the story. Along the way the reader learns a surprising amount about pond life. www.parentsintouch.co.uk Praise for Ali Sparkes's Frozen in Time, winner of the Blue Peter Book of the Year Award 'I know now what they mean by a plot that is toe-curlingly good ... brilliantly inventive and rollicking fantastical adventure' Bookbag 'Frozen in Time shows [Ali's] skill at fusing traditional children's storytelling with modern tales ... Sparkes's sci-fi conspiracy thrills will keep 21st-century kids transfixed' Books Quarterly 'It was outstanding. It blew me away' Jamie Fenlon, judge on the Blue Peter book award panel
