Sam likes being a twin. He likes having two mums. He likes cheese sandwiches and his dog and drawing comics with his friend Pea. He does not like humus – or heights . . .
His twin sister Sammie likes being a twin too. She knows that she’s perfect best friend material for somebody – the girls in her class just haven’t realised yet. And she knows that she’s the best Sam – Sam A.
Both Sam and Sammie – and everybody in their lives seems to be keeping secrets – which ones will come out?
