But are the Rainbow Boots really worth all this hassle? A hilarious school comedy from popular writer Chris Powling with illustrations from the brilliant Jim Field.

Printed on tinted paper with a dyslexia friendly font, Rainbow Boots is aimed at readers aged 9+ and has a manageable length (64 pages) and reading age (7+). Produced in association with reading experts at Catch Up, a charity which aims to address underachievement caused by literacy and numeracy difficulties.
