Bradley Trevor Greive

Since the debut of his international best-seller The Blue Day Book, Bradley Trevor Greive has sold more than 15 million copies of his much-loved books and has become a household name in more than 105 countries. A former Australian paratrooper, BTG left the army to pursue more creative misadventures. He has been bitten by wild monkeys and rabid bats and was accepted into Russia's cosmonaut training program—though those incidents were hopefully unrelated. BTG spends most of his time in a small Australian hamlet with several enormous dogs.
