It is a world much like our own, with one deadly difference: ninety-nine percent of the population is lycanthropic. When the full moon rises, humans transform into lunes, bloodthirsty beasts who cannot be reasoned with or tamed. Those few born unable to change are disparagingly known as barebacks, and live as victims of prejudice and oppression. All too often, they are targets of savage mauling and death by lunes who break the law to roam free on full-moon nights.
