Animal is set in and around a beautiful Welsh seaside town. Money is tight and the residents are fed up with their crime-infested community, so a group of renegade martial artists decide to take the law into their own hands and become hired vigilantes. In the centre of this all is Will Thomas, a martial artist and friend to the watchmen. Will is back in town after spending three years in prison for grievous bodily harm. His sole purpose is to try and win back his ex-fiancée, Stacey. Meanwhile, problems arise for the vigilantes when one of their victims turns out to be a mule for a dangerous Merseyside gang. Now the hunters have suddenly become the hunted and, in desperation, they turn to their old friend Will for help. But Will has turned over a new leaf and has managed to build the foundations for a new relationship with his Stacey. Is he willing to risk everything to help them?
Animal is a work of crime fiction, weaved with a little romance and plenty of martial arts, for readers who want a glimpse of criminals getting a taste of their own medicine. Paul is mostly influenced by James Herbert, whose writing style he emulates.
