Tom Danielson was a forty year old man, of medium height and build. He worked his daily grind at Cape Canaveral, Florida, where NASA launched the space shuttles from time to time, along with various rockets for both private and governmental concerns.
Tom had, up until this point, been living a very mundane, but comfortable life in Florida with his wife, Denise, age 35, and their two children; Joy, aged 17, and her brother Brandon, aged 16.
But one day, on the way to his car after a long day of work, a friend of his stopped him. That friend was Rick Baker, a veteran astronaut that Tom had gotten to know from the years he'd spent at NASA.
Rick hadn't been particularly chatty, rather simply saying he wanted to give him a souvenier, from some years previously, when he'd gone to the moon. Out of his jacket, Rick produced a fist-sized chunk of grey stone, which Rick confirmed to Tom was actually a chunk of the moon, taken for research purposes which had now been completed.
Tom took it, thinking it would make a fine conversation piece for his living room coffee table, thanked Rick, and headed home.
But there were a few things that Tom didn't know, and if he had, he probably wouldn't have taken the rock home with him.
Deep in Tom's ancestral past, on his mother's side, was a werewolf. This gene passed its way down the family tree, and Tom carried it, as did his children. His wife carried it as well, due to a blood transfusion she'd needed after Joy had been born. Quite conveniently, Tom had been a match with her, but in doing so, the genetic werewolf virus had written itself into her DNA as well, though it remained dormant.
The reason why the werewolf gene had remained in its passive and dormant state, noone would really be able to answer. But most parapsychologists agree that it normally takes some sort of trigger mechanism to make the gene active in an individual. Once the gene has gone active, and the body begins producing the werewolf virus in salivary glands, it is passed on in its normal, active state memorialized in dozens of Hollywood horror flicks.
The third thing that Tom didn't know was that bringing a piece of the moon into his household would qualify as a trigger.
