LoveReading View on I Stole My Genius Sister's Brain

A super-funny story of chalk-and-cheese siblings, family life and one boy’s against-the-odds mission to win a Mega Brain quiz

From the creator of I Swapped My Brother On The Internet comes this fizzily energetic feast of fun that sees aspiring inventor Keith get more than he bargained for after entering a Junior Mega Brain Quiz and winding up competing against his genius sister.

Keith is one of life’s dreamers, and something of an underdog readers will really root for. He has his sights set on going to an Inventors’ Fair in Paris, but his mum and dad just don’t have the cash. Never one to let a problem stand in his way, Keith observes how his super-smart sister Minerva (appropriately named after the Roman goddess of wisdom) has won money for some of her many achievements. And so, while “there was no Roman god Keith”, our ever-hopeful hero hits on the idea of inventing a machine to steal Min’s brain so he can win a Junior Mega Brain Quiz and use the prize money to pay for Paris. 

From attempting to drink coffee while wearing a child-genius outfit (black leggings, black polo neck and giant sunglasses), to becoming an instant TV hit with a hashtag and band of devoted followers, Keith’s story is a hilarious, heart-warming delight from start to finish, and a great read for readers who loved David Solomons’s My Brother is a Superhero series.

I Stole My Genius Sister's Brain Synopsis

Perfect for fans of Pamela Butchart and David Solomons, this is a new hilarious adventure from the creative team behind the bestselling I Swapped My Brother On The Internet.

Keith has entered the Junior Mega Brain quiz and he's determined to win. The problem is - he's not really a genius. Even worse, his sister Minerva actually is, and Keith will have to go head to head against her. Keith needs to get super smart and fast! Could he just steal Min's brain? Or will some awesome inventions, sneezing rabbits and fearsome flapjacks be the genius way to victory?
