Voiceless is an Australian think tank promoting respect and compassion for animals. Part of that endeavor is the awarding of the Voiceless Writing Prize, sponsored by Australian Ethical Investment. With a prize pool of over $20,000 it is one of the largest awards of its kind in Australia. Judged by an expert panel, the prize is awarded for Australian writing which advances the public's understanding of animal sentience, human-animal relationships, and the ethical treatment of animals. This anthology presents the very best of the bounty of entries received for the 2013 awards.
