Zack has always found school difficult. Even though he is good at maths and excellent at flicking elastic bands, trying to read and write is like trying to fight a kraken. One day, when he discovers the rest of his class infected by a mysterious sleeping sickness, Zack draws on his strengths resulting in some unexpected consequences . . . This engaging story, suitable for readers aged 8–12, explores some of the challenges faced by learners who find literacy unusually difficult. Alongside the practical difficulties of living in a world that assumes good levels of literacy, it explores some of the psychological impacts of struggling to achieve a skill that most children acquire with relative ease. Ultimately, it shows children that they can draw on their strengths and overcome the challenges in their way. Also available as a set with a supporting guide, this book operates as a fun and entertaining standalone story, as well as an educational opportunity. The range of vocabulary means it can be used flexibly, for independent, paired or whole-group reading. It is a must-have book for every classroom.
