“ Vampires, contrary to popular belief, don't incinerate when exposed to sunlight. If that were true, there would be a heck of a lot more stories about spontaneous combustion around the world. They are, however, very sensitive to sunlight and their skin cannot take long term exposure without damaging and burning it, which was painful. From Vampire Princess Rising book two of the Winters Saga ”
