Jaffy Brown is running along a street in London's East End when he comes face to face with an escaped circus animal. Plucked from the jaws of death by Mr Jamrach - explorer, entrepreneur and collector of the world's strangest creatures - the two strike up a friendship. Before he knows it, Jaffy finds himself on board a ship bound for the Dutch East Indies, on an unusual commission for Mr Jamrach. His journey - if he survives it - will push faith, love and friendship to their utmost limits.
