Try, from bestselling authors, rugby legends and best friends Rob Burrow and Kevin Sinfield is an irresistibly big-hearted picture book about a friendship between two young boys - written with Emma Adams and illustrated by Ben Whitehouse.

Meet Rob and Kevin. They play games together, laugh together and go to school together. They have lots of other friends. But Rob always has Kevin. And Kevin always has Rob.

When their teacher asks the class to think of their hero, Kevin knows exactly who to pick: the fast, brave and strong captain of the Roaring Bears rugby team! Rob, however, feels unsure. Do heroes really have to be big and strong? Before long, Rob and Kevin start to realise that perhaps being a hero isn't all about strength and muscles - it's much, much more than that . . .

From the creators of the number one bestselling With You Every Step, Try celebrates affectionate and caring friendships, showing young readers, and especially young boys, the power of friendships based in love, trust and vulnerability - and that there are many ways to be strong.
