The Waning Moon

After his father's death, Raymond seeks to find out more about his father's work with werewolves, much of which was completed in secrecy. So he enters the Central Laboratory and meets Kata, the werewolf his father discovered years ago. He is one of three werewolves in the entire world to have been discovered by science. But Kata is a special specimen... in order for the laboratory to get the most out of their research, all of Kata's needs must be met—including his voracious sexual appetite. Life at the lab has a long history of mixing work with pleasure, and it isn't long until the lives of everyone at the Central Laboratory becomes tangled up with one another.
