the legend of the Cold Ones (the twilight saga)

Vampires (also called The Cold Ones) are the primary supernatural creatures of the Twilight universe. They are immortal beings who feed and survive on the blood of humans or animals.

Vampires are one of the three known supernatural species in the Twilight series, with the others being the shape-shifters and the werewolves.

The origin of the vampire race remains a mystery. Contrary to popular belief, in the Twilight universe, vampires deviate from those of traditional myth; a fact often alluded to in the series, usually for humor. For example, all vampires have refined and perfected physical features (including their scent and voice), allowing them to lure in prey.

Their skin is flawless and textured with a marble-like substance much harder and stronger than granite. Due to the crystalline properties of their cells, when a vampire is exposed to sunlight, their body will sparkle like diamonds. For vampires who feed on human blood, their eyes reflect a deep red, as opposed to those who drink animal blood, whose eyes will reflect a medium gold color. Vampires also possess superhuman powers, such as speed and strength. Vampires also have incredibly keen senses and are able to hear for miles and see in total darkness.

Vampires are indeed immortal unless destroyed. Vampires are unable to sleep, and thus spend all days and nights awake. After transformation, a few vampires show special abilities such as foresight or telepathy. Most of them, however, do not, and show a prominent personality or physical trait magnified from their human life. Vampires are unharmed by garlic, holy items, or wooden stakes; they have reflections and shadows, and are able to walk freely in the sunlight without being physically damaged by it
