Jenson was born to a werewolf mother who mated with her vampire father during the 24 hour period in which the changes from human to vampire are still happening (meaning that the vampire is still fertile). It was a full moon, in which werewolves have a need for sex. After mating, Jenson’s mother killed the vampire. Jenson’s mother gave birth to twins – her and Rhoan.
After growing up in the Jenson pack, Riley and Rhoan were kicked out when they were teenagers, because the pack did not approve of their mixed blood.
Riley is described as not beautiful, but pretty, with red hair and charcoal eyes.
