Simon Bartram's Bob, Man on the Moon was first published in 1992 and the Bob books have become a picture book phenomenon reaching sales of 250,000 and winning Simon The Blue Peter Book Award.

To celebrate Bob's 10th Birthday, Templar have launched Simon's new picture book, Bob and the Moontree Mystery.

"Bob is truly stumped by the arrival of a mysterious Moontree growing out of crater 483. Moontree questions ping around his head - where did it come from? How did it get here? And why does Bob feel like it's his job to protect the tree and it's golden podberries?"

Watch out for forthcoming events and competitions. Simon Bartram is represented by Arena
