Oliver is a great inventor. He has brains for thinking, tools for tinkering, and a special knack for trying and trying and trying again. No problem is too big for Oliver! But when his mum suggests he invite his classmates to invent with him, Oliver isn't so sure. What if they don't like inventing? What if they don't like him? Soon, Oliver's wondering has turned into worrying, and his worrying is making it very hard to think at all. So Oliver does what Oliver does best: he invents. His mind-reading machine should put a stop to all that wondering once and for all. But when he switches it on at school and listens in, Oliver hears something surprising. Ruby is worried about her new scrunchies. Nathan is worried no one will play with him. Everyone, it turns out, is far too busy with their own worries to be thinking about Oliver at all. Worries, Oliver realizes, are a problem for everyone - and no problem is too big for him. Oliver Invents is a story-first picture book about social anxiety, friendship and the power of looking out for each other. It shows children that they are not alone in their worries, and that the best inventions of all are kindness, good friends and a big deep breath.
