A boy forms an unusual friendship with a polar bear who helps him deal with his feelings about his younger brother who is autistic.
All I want is a normal family but no, I've ended up with the brother from Weirdsville. Liam is so embarrassing, but Mum and Dad can't see that and give him all the attention. Leaving me with zero! Zilch! A big fat NOTHING!
And I'm not really sure how an enormous, funny, clumsy polar bear is going to help with all this, but he was standing on the doorstep, so I had to invite him to stay, didn't I? Well, what would you have done?
Meet Arthur and his brand new friend, Mister P - the world's most helpful polar bear!
